This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. THERMAL CHARACTERISTICS JC = 11C/W JA = 47C/W The ADV7322 is a Pb-free environmentally friendly product. It is manufactured using the most up-to-date materials and processes. The coating on the leads of each device is 100% pure Sn electroplate. The device is suitable for Pb-free applications and is able to withstand surface-mount soldering at up to 255C (5C). In addition, it is backward-compatible with conventional SnPb soldering processes. This means that the electroplated Sn coating can be soldered with Sn/Pb solder pastes at conventional reflow temperatures of 220C to 235C. 1 Analog output short circuit to any power supply or common can be of an indefinite duration. ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection.

PrA | Page 23 of 88 ADV7322 MPU PORT DESCRIPTION The ADV7322 supports a 2-wire serial (I2C-compatible) microprocessor bus driving multiple peripherals. This port operates in an open-drain configuration. Two inputs, serial data (SDA) and serial clock (SCL), carry information between any device connected to the bus and the ADV7322. Each slave device is recognized by a unique address. The ADV7322 has four possible slave addresses for both read and write operations. These are unique addresses for each device and are illustrated in Figure 44. The LSB sets either a read or write operation. Logic 1 corresponds to a read operation, while Logic 0 corresponds to a write operation. A1 is set by setting the ALSB pin of the ADV7322 to Logic 0 or Logic 1. When ALSB is set to 1, there is greater input bandwidth on the I2C lines, which allows high speed data transfers on this bus. When ALSB is set to 0, there is reduced input bandwidth on the I2C lines, which means that pulses of less than 50 ns will not pass into the I2C internal controller. This mode is recommended for noisy systems. 1 1 0 1 0 1 A1 ADDRESS CONTROL SET UP BY ALSB READ/WRITE CONTROL 0 1 WRITE READ 05067-020 Preliminary Technical Data The ADV7322 acts as a standard slave device on the bus. The data on the SDA pin is eight bits long, supporting the 7-bit addresses plus the R/W bit. It interprets the first byte as the device address and the second byte as the starting subaddress. There is a subaddress auto-increment facility. This allows data to be written to or read from registers in ascending subaddress sequence starting at any valid subaddress. A data transfer is always terminated by a stop condition. The user can also access any unique subaddress register on a one-by-one basis without having to update all the registers. Stop and start conditions can be detected at any stage during the data transfer. If these conditions are asserted out of sequence with normal read and write operations, then they cause an immediate jump to the idle condition. During a given SCL high period, the user should only issue one start condition, one stop condition, or a single stop condition followed by a single start condition. If an invalid subaddress is issued by the user, the ADV7322 will not issue an acknowledge and will return to the idle condition. If in auto-increment mode the user exceeds the highest subaddress, the following action is taken: 1. In read mode, the highest subaddress register contents are output until the master device issues a no-acknowledge. This indicates the end of a read. A no-acknowledge condition is when the SDA line is not pulled low on the ninth pulse. In write mode, the data for the invalid byte is not loaded into any subaddress register, a no-acknowledge is issued by the ADV7322, and the part returns to the idle condition. X Figure 44. ADV7322 Slave Address = 0xD4 2. To control the various devices on the bus, the following protocol must be followed. First the master initiates a data transfer by establishing a start condition, defined by a high-to-low transition on SDA while SCL remains high. This indicates that an address/data stream will follow. All peripherals respond to the start condition and shift the next eight bits (7-bit address + R/W bit). The bits are transferred from MSB down to LSB. The peripheral that recognizes the transmitted address responds by pulling the data line low during the ninth clock pulse. This is known as an acknowledge bit. All other devices withdraw from the bus at this point and maintain an idle condition. The idle condition is where the device monitors the SDA and SCL lines waiting for the start condition and the correct transmitted address. The R/W bit determines the direction of the data. Logic 0 on the LSB of the first byte means that the master will write information to the peripheral. Logic 1 on the LSB of the first byte means that the master will read information from the peripheral. Before writing to the subcarrier frequency registers, it is a requirement that the ADV7322 is reset at least once after power-up. The four subcarrier frequency registers must be updated, starting with subcarrier frequency register 0 through subcarrier frequency register 3. The subcarrier frequency will not update until the last subcarrier frequency register byte has been received by the ADV7322. Figure 45 illustrates an example of data transfer for a write sequence and the start and stop conditions. Figure 46 shows bus write and read sequences. Rev.

Read and Write Sequence Rev. PrA | Page 25 of 88 ADV7322 REGISTER ACCESS The MPU can write to or read from all of the registers of the ADV7322 except the subaddress registers, which are write only registers. The subaddress register determines which register the next read or write operation will access. All communications with the part through the bus start with an access to the subaddress register. A read/write operation is then performed from/to the target address, which increments to the next address until a stop command is performed on the bus. Preliminary Technical Data REGISTER PROGRAMMING The following tables describe the functionality of each register. All registers can be read from as well as written to, unless otherwise stated. SUBADDRESS REGISTER (SR7 TO SR0) The communication register is an 8-bit write-only register. After the part is accessed over the bus and a read/write operation is selected, the subaddress is set up. The subaddress register determines to/from which register the operation takes place. Reg. Reset Values (Shaded) 0xFC Table 7.

ADV7322 input on Pins Y7 to Y0 and the CrCb data is input on Pins C7 to C0. In 4:4:4 input mode, Y data is input on Pins Y7 to Y0, Cb data is input on Pins C7 to C0, and Cr data is input on Pins S7 to S0. If the YCrCb data does not conform to SMPTE 293M (525p), ITU-R BT.1358M (625p), SMPTE 274M[1080i], SMPTE 296M[720p], SMPTE 240M(1035i) or BTA-T1004/1362, the async timing mode must be used. RGB data can only be input in 4:4:4 format in PS input mode or in HDTV input mode when HD RGB input is enabled. G data is input on Pins Y7 to Y0, R data is input on Pins S7 to S0, and B data is input on Pins C7 to C0. The clock signal must be input on Pin CLKIN_A.

Input standards supported are ITU-R BT.601/656. In 16-bit input mode, the Y pixel data is input on Pins S7 to S0 and CrCb data is input on Pins Y7 to Y0 (see Table 21). 16-Bit Mode Operation When Register 0x01 Bit 7 = 0, CrCb data is input on the Y bus and Y data is input on the S bus. When Register 0x01 Bit 7 = 1, CrCb data is input on the C bus and Y data is input on Y bus. The 27 MHz clock input must be input on Pin CLKIN_A. Input sync signals are input on the S_VSYNC, S_HSYNC, and S_BLANK pins. Table 21.

In 4:2:2 input mode, the HD Y data is input on Pins Y7 to Y0 and the HD CrCb data is input on Pins C7 to C0. If PS 4:2:2 data is interleaved onto a single 10-bit bus, Pins Y7 to Y0 are used for the input port. The input data is to be input at 27 MHz, with the data being clocked on the rising and falling edge of the input clock. The input mode register at Address 0x01 is set accordingly. If the YCrCb data does not conform to SMPTE 293M (525p), ITU-R BT.1358M (625p), SMPTE 274M[1080i], SMPTE 296M[720p], SMPTE 240M(1035i) or BTA-T1004, the async timing mode must be used.

Timing control signals for HSYNC, VSYNC, and BLANK must be programmed by the user. Macrovision and programmable oversampling rates are not available in async timing mode. ADV7322 In async mode, the PLL must be turned off [Subaddress 0x00, Bit 1 = 1]. Register 0x10 should be programmed to 0x01. Figure 57 and Figure 58 show examples of how to program the ADV7322 to accept a high definition standard other than SMPTE 293M, SMPTE 274M, SMPTE 296M, or ITU-R BT.1358. Table 26 must be followed when programming the control signals in async timing mode. For standards that do not require a trisync level, P_BLANK must be tied low at all times. Table 26.

PrA | Page 43 of 88 05067-034 ADV7322 HD TIMING RESET A timing reset is achieved by toggling the HD timing reset control bit [Subaddress 0x14, Bit 0] from 0 to 1. In this state the horizontal and vertical counters will remain reset. When this bit is set back to 0, the internal counters will commence counting again. The minimum time the pin has to be held high is one clock cycle; otherwise, this reset signal might not be recognized. This timing reset applies to the HD timing counters only. b. Preliminary Technical Data In subcarrier phase reset, a low-to-high transition on the RTC_SCR_TR pin (Pin 31) will reset the subcarrier phase to zero on the field following the subcarrier phase reset when the SD RTC/TR/SCR control bits at Address 0x44 are set to 01. This reset signal must be held high for a minimum of one clock cycle. Since the field counter is not reset, it is recommended that the reset signal is applied in Field 7 [PAL] or Field 3 [NTSC]. The reset of the phase will then occur on the next field, i.e., Field 1, being lined up correctly with the internal counters. The field count register at Address 0x7B can be used to identify the number of the active field. c. In RTC mode, the ADV7322 can be used to lock to an external video source. The real-time control mode allows the ADV7322 to automatically alter the subcarrier frequency to compensate for line length variations. When the part is connected to a device that outputs a digital data stream in the RTC format, such as an ADV7183A video decoder (see Figure 61), the part will automatically change to the compensated subcarrier frequency on a line by line basis. This digital data stream is 67 bits wide and the subcarrier is contained in Bits 0 to 21. Each bit is two clock cycles long. Write 0x00 into all four subcarrier frequency registers when this mode is used. SD REAL-TIME CONTROL, SUBCARRIER RESET, AND TIMING RESET [Subaddress 0x44, Bits 2 and 1] Together with the RTC_SCR_TR pin and SD Mode Register 3 [Address 0x44, Bits 1 and 2], the ADV7322 can be used in (a) timing reset mode, (b) subcarrier phase reset mode, or (c) RTC mode. a. A timing reset is achieved in a low-to-high transition on the RTC_SCR_TR pin (Pin 31). In this state, the horizontal and vertical counters will remain reset. Upon releasing this pin (set to low), the internal counters will commence counting again, the field count will start on Field 1, and the subcarrier phase will be reset. The minimum time the pin must be held high is one clock cycle; otherwise, this reset signal might not be recognized. This timing reset applies to the SD timing counters only.

Preliminary Technical Data signal usually occurs after the total number of lines/fields is reached. Conventionally this means that the output video will have corrupted field signals, one generated by the incoming video and one generated when the internal lines/field counters reach the end of a field. When the VCR FF/RW sync control is enabled [Subaddress 0x42, Bit 5], the lines/fields counters are updated according to the incoming VSYNC signal, and the analog output matches the incoming VSYNC signal. This control is available in all slave timing modes except Slave Mode 0. SD VCR FF/RW SYNC [Subaddress 0x42, Bit 5] In DVD record applications where the encoder is used with a decoder, the VCR FF/RW sync control bit can be used for nonstandard input video, i.e., in fast forward or rewind modes. In fast forward mode, the sync information at the start of a new field in the incoming video usually occurs before the correct number of lines/fields is reached; in rewind mode, this sync RESET DACs A, B, C XXXXXX OFF VALID VIDEO DIGITAL TIMING XXXXXX DIGITAL TIMING SIGNALS SUPPRESSED TIMING ACTIVE 05067-039 PIXEL DATA VALID Figure 62. RESET Timing Sequence Rev. PrA | Page 46 of 88 Preliminary Technical Data VERTICAL BLANKING INTERVAL The ADV7322 accepts input data that contains VBI data [CGMS, WSS, VITS, and so on] in SD and HD modes. For SMPTE 293M [525p] standards, VBI data can be inserted on Lines 13 to 42 of each frame, or on Lines 6 to 43 for the ITU-R BT.1358 [625p] standard. For SD NTSC this data can be present on Lines 10 to 20, and in PAL on Lines 7 to 22. If VBI is disabled [Address 0x11, Bit 4 for HD; Address 0x43, Bit 4 for SD], VBI data is not present at the output and the entire VBI is blanked. These control bits are valid in all master and slave modes. In Slave Mode 0, if VBI is enabled, the blanking bit in the EAV/SAV code is overwritten. It is possible to use VBI in this timing mode as well. In Slave Mode 1 or 2, the BLANK control bit must be set to enabled [Address 0x4A, Bit 3] to allow VBI data to pass through the ADV7322. Otherwise, the ADV7322 automatically blanks the VBI to standard. If CGMS is enabled and VBI is disabled, the CGMS data will nevertheless be available at the output. See Appendix 1--Copy Generation Management System. ADV7322 SUBCARRIER FREQUENCY REGISTERS [Subaddresses 0x4C to 0x4F] Four 8-bit registers are used to set up the subcarrier frequency. The value of these registers is calculated using the equation Subcarrier Frequency Register = Number of subcarrier periods in one video line Number of 27 MHz clk cycles in one video line where the sum is rounded to the nearest integer. For example, in NTSC mode 227.5 32 Subcarrier Re gister Value = x 2 = 569408543 1716 where: Subcarrier Register Value = 0x21F07C1F SD FSC Register 0: 0x1F SD FSC Register 1: 0x7C SD FSC Register 2: 0xF0 SD FSC Register 3: 0x21 See the MPU Port Description section for more details on how to access the subcarrier frequency registers. x 2 32 Programming the FSC The Subcarrier Register Value is shared across 4 FSC registers as shown above. To load the value into the encoder, users must write to the FSC registers in sequence, starting with FSC0. The value is not loaded until the FSC4 write is complete. Note that the ADV7322 power-up value for FSC0 = 0x1E. For precise NTSC FSC, write 0x1F to this register. Rev.

The UV filter supports several different frequency responses including six low-pass responses, a CIF response, and a QCIF response, as shown in Figure 35 and Figure 36. If SD SSAF gain is enabled, there is the option of 12 responses in the range -4 dB to +4 dB [Subaddress 0x47, Bit 4]. The desired response can be chosen by the user by programming the correct value via the I2C [Subaddress 0x62]. The variation of frequency responses are shown in Figure 32 and Figure 33. In addition to the chroma filters listed in Table 27, the ADV7322 contains an SSAF filter specifically designed for and applicable to the color difference component outputs, U and V. 1 Pass-band ripple is the maximum fluctuation from the 0 dB response in the pass band, measured in dB. The pass band is defined to have 0 Hz to fc (Hz) frequency limits for a low-pass filter, and 0 Hz to f1 (Hz) and f2 (Hz) to infinity for a notch filter, where fc, f1, and f2 are the -3 dB points. 2 3 dB bandwidth refers to the -3 dB cutoff frequency.

Table 29 shows sample color values to be programmed into the color registers when Output Standard Selection is set to EIA 770.2. Rev. PrA | Page 50 of 88 Preliminary Technical Data This is reflected in the preprogrammed values for GY = 0x138B, GU = 0x93, GV = 0x3B, BU = 0x248, and RV = 0x1F0. Again if RGB matrix is enabled and another input standard is used (SD or PS), the scale values for GY, GU, GV, BU, and RV must be adjusted according to this input standard color space. The user should consider the fact that the color component conversion might use different scale values. For example, SMPTE 293M uses the following conversion: R = Y + 1.402Pr G = Y - 0.714Pr - 0.344Pb B = Y + 1.773Pb ADV7322 Upon power-up, the RGB matrix is programmed with the default values in Table 31. Table 31. RGB Matrix Default Values Address 0x03 0x04 0x05 0x06 0x07 0x08 0x09 Default 0x03 0xF0 0x4E 0x0E 0x24 0x92 0x7C The manual RGB matrix adjust feature can be used to control the HD output levels in cases where the video output does not conform to the standard due to altering the DAC output stages such as termination resistors. The programmable RGB matrix is used for external HD/PS data and is not functional when internal test patterns are enabled. Adjusting Registers 0x05 to 0x09 requires the manual RGB matrix adjust to be enabled [Register 0x02, Bit 3 =1]. When the manual RGB matrix adjust feature is not enabled, the ADV7322 automatically scales YCrCb inputs to all standards supported by this part as selected by input mode Register 0x01 [6:4]. SD Luma and Color Control [Subaddresses 0x5C, 0x5D, 0x 5E, 0x 5F] SD Y Scale, SD Cr Scale, and SD Cb Scale are three 10-bit-wide control registers that scale the Y, Cb, and Cr output levels. Each of these registers represents the value required to scale the Cb or Cr level from 0.0 to 2.0 and the Y level from 0.0 to 1.5 of its initial level. The value of these 10 bits is calculated using the following equation: Y, Cr, or Cb Scalar Value = Scale Factor x 512 Programming the RGB Matrix If custom manipulation of coefficients is required, The RGB matrix is enabled in Address 0x02, Bit 3. The output should be set to RGB [Address 0x02, Bit 5], sync on PrPb should be disabled (default) [Address 0x15, Bit 2], and sync on RGB is optional [Address 0x02, Bit 4]. GY at Addresses 0x03 and 0x05 control the green signal output levels. BU at Addresses 0x04 and 0x08 control the blue signal output levels, and RV at Addresses 0x04 and 0x09 control the red signal output levels. To control YPrPb output levels, YUV output should be enabled [Address 0x02, Bit 5]. In this case GY [Address 0x05; Address 0x03, Bits 0 and 1] is used for the Y output, RV [Address 0x09; Address 0x04, Bits 0 and 1] is used for the Pr output, and BU [Address 0x08; Address 0x04, Bits 2 and 3] is used for the Pb output. If RGB output is selected, the RGB matrix scaler uses the following equations: G = GY x Y + GU x Pb + GV x Pr B = GY x Y + BU x Pb R = GY x Y + RV x Pr For example, Scale Factor = 1.18 Y, Cb, or Cr Scale Value = 1.18 x 512 = 665.6 Y, Cb, or Cr Scale Value = 665 (rounded to the nearest integer) Y, Cb, or Cr Scale Value = 1010 0110 01b Address 0x5C, SD LSB Register = 0x15 Address 0x5D, SD Y Scale Register = 0xA6 Address 0x5E, SD Cb Scale Register = 0xA6 Address 0x5F, SD Cr Scale Register = 0xA6 Note that this feature affects all interlaced output signals, i.e., CVBS, Y-C, YPrPb, and RGB. SD Hue Adjust Value [Subaddress 0x60] If YPrPb output is selected, the following equations are used: Y = GY x Y U = BU x Pb V = RV x Pr The hue adjust value is used to adjust the hue on the composite and chroma outputs. These eight bits represent the value required to vary the hue of the video data, i.e., the variance in phase of the subcarrier during active video with respect to the phase of the subcarrier during the color burst. The ADV7322 provides a range of 22.5 Rev. PrA | Page 51 of 88 ADV7322 increments of 0.17578125. For normal operation (zero adjustment), this register is set to 0x80. Values 0xFF and 0x00 represent the upper and lower limits (respectively) of adjustment attainable. Hue Adjust () = 0.17578125 (HCRd - 128) for positive hue adjust value. For example, to adjust the hue by +4, write 0x97 to the Hue Adjust Value register: 4 + 128 = 105d = 0 x97 . 0.17578125 where the sum is rounded to the nearest integer. To adjust the hue by -4, write 0x69 to the Hue Adjust Value register: -4 + 128 = 105d = 0 x69 0.17578125 where the sum is rounded to the nearest integer. For example, Preliminary Technical Data 1.

This brightness level may be added onto the scaled Y data. For NTSC with pedestal, the setup can vary from 0 IRE to 22.5 IRE. For NTSC without pedestal and PAL, the setup can vary from -7.5 IRE to +15 IRE. The brightness control register is an 8-bit register. Seven bits of this 8-bit register are used to control the brightness level. This brightness level can be a positive or negative value. 1 Values in the range from 0x3F to 0x44 might result in an invalid output signal. Rev.

Programmable DAC Gain--Positive and Negative Gain In case A, the video output signal is gained. The absolute level of the sync tip and blanking level both increase with respect to the reference video output signal. The overall gain of the signal is increased from the reference signal. In case B, the video output signal is reduced. The absolute level of the sync tip and blanking level both decrease with respect to the reference video output signal. The overall gain of the signal is reduced from the reference signal. The range of this feature is specified for 7.5% of the nominal output from the DACs. For example, if the output current of the DAC is 4.33 mA, the DAC tune feature can change this output current from 4.008 mA (-7.5%) to 4.658 mA (+7.5%). The reset value of the vid_out_ctrl registers is 0x00; therefore, nominal DAC current is output. The following table is an example of how the output current of the DACs varies for a nominal 4.33 mA output current. Gamma correction is available for SD and HD video. For each standard, there are twenty 8-bit-wide registers. They are used to program the gamma correction curves A and B. HD gamma curve A is programmed at Addresses 0x24 to 0x2D, and HD gamma curve B is programmed at 0x2E to 0x7. SD gamma curve A is programmed at Addresses 0x66 to 0x6F, and SD gamma curve B is programmed at Addresses 0x70 to 0x79. Generally gamma correction is applied to compensate for the nonlinear relationship between signal input and brightness level output (as perceived on the CRT). It can also be applied wherever nonlinear processing is used. Gamma correction uses the function Signal OUT = (Signal IN ) where = gamma power factor. Gamma correction is performed on the luma data only. The user may choose either of two curves, curve A or curve B. At any one time, only one of these curves can be used. The response of the curve is programmed at 10 predefined locations. In changing the values at these locations, the gamma curve can be modified. Between these points, linear interpolation is used to generate intermediate values. Considering the curve to have a total length of 256 points, the 10 locations are at 24, 32, 48, 64, 80, 96, 128, 160, 192, and 224. Locations 0, 16, 240, and 255 are fixed and cannot be changed. Rev.

PrA | Page 55 of 88 ADV7322 HD SHARPNESS FILTER AND ADAPTIVE FILTER CONTROLS [Subaddresses 0x20, 0x38 to 0x3D] Preliminary Technical Data The derivative of the incoming signal is compared to the three programmable threshold values: HD adaptive filter threshold A, B, and C. The recommended threshold range is from 16 to 235, although any value in the range of 0 to 255 can be used. The edges can then be attenuated with the settings in HD adaptive filter gain 1, 2, and 3 registers and HD sharpness filter gain register. According to the settings of the HD adaptive filter mode control, there are two adaptive filter modes available: 1. Mode A is used when adaptive filter mode is set to 0. In this case, Filter B (LPF) will be used in the adaptive filter block. Also, only the programmed values for Gain B in the HD sharpness filter gain and HD adaptive filter gain 1, 2, and 3 are applied when needed. The Gain A values are fixed and cannot be changed. Mode B is used when adaptive filter mode is set to 1. In this mode, a cascade of Filter A and Filter B is used. Both settings for Gain A and Gain B in the HD sharpness filter gain and HD adaptive filter gain 1, 2, and 3 become active when needed. There are three filter modes available on the ADV7322: sharpness filter mode and two adaptive filter modes. HD Sharpness Filter Mode To enhance or attenuate the Y signal in the frequency ranges shown in Figure 72, the following register settings must be used: HD sharpness filter must be enabled and HD adaptive filter enable must be set to disabled. To select one of the 256 individual responses, the corresponding gain values, which range from -8 to +7, for each filter must be programmed into the HD sharpness filter gain register at Address 0x20. HD Adaptive Filter Mode The HD adaptive filter threshold A, B, and C registers, the HD adaptive filter gain 1, 2, and 3 registers, and the HD sharpness gain register are used in adaptive filter mode. To activate the adaptive filter control, the HD sharpness filter and the HD adaptive filter must be enabled. 2. 1.4 1.3 1.2 1.4 1.3 1.2 MAGNITUDE RESPONSE (Linear Scale) 1.5 SHARPNESS AND ADAPTIVE FILTER CONTROL BLOCK 1.5 1.6 1.5 1.4 1.3 1.2 1.1 1.0 MAGNITUDE INPUT SIGNAL: STEP 1.1 1.0 0.9 0.8 0.7 0.6 0.5 FREQUENCY (MHz) FILTER A RESPONSE (Gain Ka) MAGNITUDE 1.1 1.0 0.9 0.8 0.7 0.6 0.5 FREQUENCY (MHz) FILTER B RESPONSE (Gain Kb) 0 2 FREQUENCY RESPONSE IN SHARPNESS FILTER MODE WITH Ka = 3 AND Kb = 7 Figure 72.

A filter block selects the high frequency, low amplitude components of the incoming signal [DNR input select]. The absolute value of the filter output is compared to a programmable threshold value ['DNR threshold control]. There are two DNR modes available: DNR mode and DNR sharpness mode. In DNR mode, if the absolute value of the filter output is smaller than the threshold, it is assumed to be noise. A programmable amount [coring gain border, coring gain data] of this noise signal will be subtracted from the original signal. In DNR sharpness mode, if the absolute value of the filter output is less than the programmed threshold, it is assumed to be noise, as before. Otherwise, if the level exceeds the threshold, now being identified as a valid signal, a fraction of the signal [coring gain border, coring gain data] will be added to the original signal to boost high frequency components and sharpen the video image. In MPEG systems, it is common to process the video information in blocks of 8 pixels x 8 pixels for MPEG2 systems, or 16 pixels x 16 pixels for MPEG1 systems [block size control]. DNR can be applied to the resulting block transition areas that are known to contain noise. Generally, the block transition area contains two pixels. It is possible to define this area to contain four pixels [border area]. It is also possible to compensate for variable block positioning or differences in YCrCb pixel timing with the use of the DNR block offset The digital noise reduction registers are three 8-bit registers. They are used to control the DNR processing. 05067-076 Figure 75.

DNR Input Select DNR MODE CONTROL [Address 0x65, Bit 4] This bit controls the DNR mode selected. Logic 0 selects DNR mode; Logic 1 selects DNR sharpness mode. DNR works on the principle of defining low amplitude, high frequency signals as probable noise and subtracting this noise from the original signal. In DNR mode, it is possible to subtract a fraction of the signal that lies below the set threshold, assumed to be noise, from the original signal. The threshold is set in DNR Register 1. When DNR sharpness mode is enabled, it is possible to add a fraction of the signal that lies above the set threshold to the LUMA CHANNEL WITH ACTIVE VIDEO EDGE DISABLED 100 IRE When the active video edge feature is enabled, the first three pixels and the last three pixels of the active video on the luma channel are scaled so that maximum transitions on these pixels are not possible. The scaling factors are x1/8, x1/2, and x7/8. All other active video passes through unprocessed. SAV/EAV STEP EDGE CONTROL The ADV7322 has the capability of controlling fast rising and falling signals at the start and end of active video to minimize ringing. An algorithm monitors SAV and EAV and determines when the edges are rising or falling too fast. The result is reduced ringing at the start and end of active video for fast transitions. Subaddress 0x42, Bit 7 = 1, enables this feature. LUMA CHANNEL WITH ACTIVE VIDEO EDGE ENABLED 100 IRE 87.5 IRE 50 IRE Figure 81. Example of Active Video Edge Functionality Rev.

The ADV7322 can be used with an external VREF (AD1580). The RSET resistors are connected between the RSET pins and AGND and are used to control the full-scale output current and, therefore, the DAC voltage output levels. For full-scale output, RSET must have a value of 3040 . The RSET values should not be changed. RLOAD has a value of 300 for full-scale output.

Analog Devices produces a range of suitable op amps for this application, for example the AD8061. More information on line driver buffering circuits is given in the relevant op amps' data sheets. An optional analog reconstruction low-pass filter (LPF) may be required as an anti-imaging filter if the ADV7322 is connected to a device that requires this filtering. The filter specifications vary with the application. Table 36.

Power planes should encompass a digital power plane and an analog power plane. The analog power plane should contain the DACs and all associated circuitry, VREF circuitry. The digital power plane should contain all logic circuitry. The analog and digital power planes should be individually connected to the common power plane at a single point through a suitable filtering device, such as a ferrite bead. DAC output traces on a PCB should be treated as transmission lines. It is recommended that the DACs be placed as close as possible to the output connector, with the analog output traces being as short as possible (less than 3 inches). The DAC termination resistors should be placed as close as possible to the DAC outputs and should overlay the PCB's ground plane. As well as minimizing reflections, short analog output traces will reduce noise pickup due to neighboring digital circuitry. To avoid crosstalk between the DAC outputs, it is recommended that as much space as possible be left between the tracks of the individual DAC output pins. The addition of ground tracks between outputs is also recommended. GAIN (dB) 12n 10n -40 -50 10M 100M FREQUENCY (Hz) 2n -240 0 1G Figure 88.

Optimum performance is achieved by the use of 10 nF and 0.1 F ceramic capacitors. Each group of VAA, VDD, or VDD_IO pins should be individually decoupled to ground. This should be done by placing the capacitors as close as possible to the device with the capacitor leads as short as possible, thus minimizing lead inductance. A 1 F tantalum capacitor is recommended across the VAA supply in addition to 10 nF ceramic. See the circuit layout in Figure 90. -40 -50 10M 100M FREQUENCY (Hz) Figure 89. Filter Plot for Output Filter for HDTV, 2x Oversampling PCB BOARD LAYOUT The ADV7322 is optimally designed for lowest noise performance, both radiated and conducted noise. To complement the excellent noise performance of the ADV7322, it is imperative that great care be given to the PC board layout. The layout should be optimized for lowest noise on the ADV7322 power and ground lines. This can be achieved by shielding the digital inputs and providing good decoupling. The lead length between groups of VAA and AGND, VDD and DGND, and VDD_IO and GND_IO pins should be kept as short as possible to minimized inductive ringing. It is recommended that a 4-layer printed circuit board is used, with power and ground planes separating the layer of the signal carrying traces of the components and solder side layer. Component placement should be carefully considered in order to separate noisy circuits, such as crystal clocks, high speed logic circuitry, and analog circuitry. 05067-090 -60 1M Digital Signal Interconnect The digital signal lines should be isolated as much as possible from the analog outputs and other analog circuitry. Digital signal lines should not overlay the analog power plane. Due to the high clock rates used, avoid long clock lines to the ADV7322 to minimize noise pickup. Any active pull-up termination resistors for the digital inputs should be connected to the digital power plane and not the analog power plane. Analog Signal Interconnect Locate the ADV7322 as close as possible to the output connectors to minimize noise pickup and reflections due to impedance mismatch. Rev. PrA | Page 63 of 88 ADV7322 For optimum performance, the analog outputs should each be source and load terminated, as shown in Figure 90. The termination resistors should be as close as possible to the ADV7322 to minimize reflections. Preliminary Technical Data For optimum performance, it is recommended that all decoupling and external components relating to the ADV7322 be located on the same side of the PCB and as close as possible to the ADV7322. Any unused inputs should be tied to ground.

Using the vertical blanking interval 525p system, 525p CGMS conforms to the CGMS-A EIA-J CPR1204-1 (March 1998) transfer method of video identification information and to the IEC61880 (1998) 525p/60 video system's analog interface for the video and accompanying data. When PS CGMS is enabled [Subaddress 0x12, Bit 6 = 1], CGMS data is inserted on Line 41. The 525p CGMS data registers are at Addresses 0x21, 0x22, and 0x23. 625p 720p System CGMS data is applied to Line 24 of the luminance vertical blanking interval. 1080i System CGMS data is applied to Line 19 and Line 582 of the luminance vertical blanking interval. CGMS FUNCTIONALITY The 625p CGMS conforms to the IEC62375 (2004) 625p/50 video system's analog interface for the video and accompanying data using the vertical blanking interval. When PS CGMS is enabled [Subaddress 0x12, Bit 6 = 1], CGMS data is inserted on Line 43. The 625p CGMS data registers are at Addresses 0x22, and 0x23. If SD CGMS CRC [Address 0x59, Bit 4] or PS/HD CGMS CRC [Subaddress 0x12, Bit 7] is set to Logic 1, the last six bits, C19 to C14, which comprise the 6-bit CRC check sequence, are calculated automatically on the ADV7322 based on the lower 14 bits (C0 to C13) of the data in the data registers and output with the remaining 14 bits to form the complete 20 bits of the CGMS data. The calculation of the CRC sequence is based on the polynomial x6 + x + 1 with a preset value of 111111. If SD CGMS CRC [Address 0x59, Bit 4] and PS/HD CGMS CRC [Address 0x12, Bit 7] are set to Logic 0, all 20 bits (C0 to C19) are output directly from the CGMS registers (no CRC is calculated, must be calculated by the user). HD CGMS [Address 0x12, Bit 6] The ADV7322 supports Copy Generation Management System (CGMS) in HDTV mode (720p and 1080i) in accordance with EIAJ CPR-1204-2. The HD CGMS data registers are found at Addresses 0x021, 0x22, and 0x23. SD CGMS Data Registers 2 to 0 [Subaddresses 0x59, 0x5A, 0x5B] The ADV7322 supports Copy Generation Management System (CGMS), conforming to the standard. CGMS data is transmitted on Line 20 of the odd fields and Line 283 of even fields. Bits C/W05 and C/W06 control whether CGMS data is output on odd and even fields. CGMS data can be transmitted only when the ADV7322 is configured in NTSC mode. The CGMS data is 20 bits long, and the function of each of these bits is as shown in the following table. The CGMS data is preceded by a reference pulse of the same amplitude and duration as a CGMS bit; see Figure 93. Rev.

If SD WSS [Address 0x59, Bit 7] is set to Logic 1, it enables the WSS data to be transmitted on Line 23.

The ADV7322 supports wide screen signaling (WSS) conforming to the standard. WSS data is transmitted on Line 23. WSS data can be transmitted only when the device is configured in PAL mode.

WSS Waveform Diagram Rev. PrA | Page 68 of 88 Preliminary Technical Data APPENDIX 3--SD CLOSED CAPTIONING [Subaddresses 0x51 to 0x54] ADV7322 The ADV7322 supports closed captioning conforming to the standard television synchronizing waveform for color transmission. Closed captioning is transmitted during the blanked active line time of Line 21 of the odd fields and Line 284 of the even fields. Closed captioning consists of a 7-cycle sinusoidal burst that is frequency and phase locked to the caption data. After the clock run-in signal, the blanking level is held for two data bits and is followed by Logic 1 start bit. Sixteen bits of data follow the start bit. These consist of two 8-bit bytes, seven data bits, and one odd parity bit. The data for these bytes is stored in the SD closed captioning registers [Addresses 0x53 to 0x54]. The ADV7322 also supports the extended closed captioning operation, which is active during even fields and encoded on Scan Line 284. The data for this operation is stored in the SD closed captioning registers [Addresses 0x51 to 0x52]. All clock run-in signals and timing to support closed captioning on Lines 21 and 284 are generated automatically by the ADV7322. All pixels inputs are ignored during Lines 21 and 284 if closed captioning is enabled. FCC Code of Federal Regulations (CFR) 47 section 15.119 and EIA608 describe the closed captioning information for Lines 21 and 284. The ADV7322 uses a single buffering method. This means that the closed captioning buffer is only 1 byte deep; therefore, there will be no frame delay in outputting the closed captioning data, unlike other 2-byte-deep buffering systems. The data must be loaded one line before it is output on Line 21 and Line 284. A typical implementation of this method is to use VSYNC to interrupt a microprocessor, which in turn will load the new data (two bytes) in every field. If no new data is required for transmission, 0s must be inserted in both data registers; this is called nulling. It is also important to load control codes, all of which are double bytes, on Line 21, or a TV will not recognize them. If there is a message like "Hello World" that has an odd number of characters, it is important to pad it out to even to get "end of caption" 2-byte control code to land in the same field. 10.5 0.25s 12.91s 7 CYCLES OF 0.5035MHz CLOCK RUN-IN TWO 7-BIT + PARITY ASCII CHARACTERS (DATA) S T A R T P A R I T Y P A R I T Y 50 IRE D0-D6 D0-D6 BYTE 0 40 IRE REFERENCE COLOR BURST (9 CYCLES) FREQUENCY = FSC = 3.579545MHz AMPLITUDE = 40 IRE 10.003s 27.382s 33.764 s BYTE 1 Figure 97.
