1.5 DAC features
UDA1380
The DAC part is equipped with a stereo line output and a headphone driver output. The headphone driver is capable of driving a 16 load. The headphone driver is also capable of driving a headphone without the need for external DC decoupling capacitors, since the headphone can be connected to a pin VREF(HP) on the chip. In addition, there is a built-in short-circuit protection for the headphone driver output which, in case of short-circuit, limits the current through the operational amplifiers and signals the event via its L3-bus or I2C-bus register. The UDA1380 also supports an application mode in which the coder-decoder itself is not running, but an analog signal, for instance coming from an FM tuner, can be controlled in gain, and applied to the output via the headphone driver and line outputs. The UDA1380 supports the I2S-bus data format with word lengths of up to 24 bits, the MSB-justified data format with word lengths of up to 24 bits and the LSB-justified serial data format with word lengths of 16, 18, 20 or 24 bits (LSB-justified 24 bits is only supported for the output interface). The UDA1380 has sound processing features in playback mode, de-emphasis, volume, mute, bass boost and treble which can be controlled by the L3-bus or I2C-bus interface.
* DAC plus interpolator can run at either WSPLL (regenerating the clock from WSI) or at SYSCLK * Separate digital logarithmic volume control for left and right channels via L3-bus or I2C-bus from 0 to -78 dB in steps of 0.25 dB * Digital tone control, bass boost and treble via L3-bus or I2C-bus interface * Digital de-emphasis for sample frequencies of: 32, 44.1, 48 and 96 kHz via L3-bus or I2C-bus interface * Cosine roll-off soft mute function * Output signal polarity control via L3-bus or I2C-bus interface * Digital mixer for mixing ADC output signal and digital serial input signal, if they run at the same sampling frequency. 2 APPLICATIONS
This audio coder-decoder is suitable for home and portable applications like MD, CD and MP3 players. 3 GENERAL DESCRIPTION
The UDA1380 is a stereo audio coder-decoder, available in TSSOP32 (UDA1380TT) and HVQFN32 (UDA1380HN) packages. All functions and features are identical for both package versions. The term `UDA1380' in this document refers to both UDA1380TT and UDA1380HN, unless particularly specified. The front-end of the UDA1380 is equipped with a stereo line input, which has a PGA control, and a mono microphone input with an LNA and a VGA. The digital decimation filter is equipped with an AGC which can be used in case of voice-recording.

8 8.1 FUNCTIONAL DESCRIPTION Clock modes 8.1.1 WSPLL REQUIREMENTS
UDA1380
There are two clock systems: * A SYSCLK signal, coming from the system or the SSA1 chip * A WSPLL which generates the internal clocks from the incoming WSI signal. The system frequency applied to pin SYSCLK is selectable. The options are 256fs, 384fs, 512fs and 768fs. The system clock must be locked in frequency to the digital interface signals. Remark: Since there is neither a fixed reference clock available in the IC itself, nor a fixed clock available in the system the IC is in, there is no auto sample rate conversion detection circuitry. The system can run in several modes, using the two clock systems: * Both the DAC and the ADC part can run at the applied SYSCLK input. In this case the WSPLL is powered-down * The ADC can run at the SYSCLK input, and at the same time the DAC part can run (at a different frequency) at the clock re-generated from the WSI signal * The ADC and the DAC can both run at the clock regenerated from the WSI signal.
The WSPLL is meant to lock onto the WSI input signal, and regenerates a 256fs and 128fs signal for the FSDAC and the interpolator core (and for the decimator if needed). Since the operating range of the WSPLL is from 75 to 150 MHz, the complete range of 8 to 100 kHz sampling frequency must be divided into smaller parts, as given in Table 1, using Fig.4 as a reference. This means that the user must set the input range of the WSI input signal. In case the SYSCLK is used for clocking the complete system (decimator including interpolator) the WSPLL must be powered-down with bit ADC_CLK via the L3-bus or I2C-bus. The SEL_LOOP_DIV[1:0] can be controlled by the PLL1 and PLL0 bits in the L3-bus or I2C-bus register.

8.1.2 CLOCK DISTRIBUTION
UDA1380
Figure 5 shows the main clock distribution for the SYSCLK domain and the WSPLL clock domain. For power saving reasons each clock signal inside the system must be controlled and enabled via a separate bit in the L3-bus and I2C-bus registers (ADC_CLK). The DAC part of the UDA1380 can operate from 8 to 100 kHz sampling frequency (fs). This applies to the DAC part only; the ADC part can run from 8 to 55 kHz.

8.2 ADC analog front-end 8.2.1
UDA1380
APPLICATIONS AND POWER-DOWN MODES
The analog front-end of the UDA1380 consists of one stereo ADC with a selector in front of it (see Fig.6). Using this selector one can either select the microphone input with the microphone amplifier (LNA) with a fixed 29 dB gain and VGA (no PGA, since a real microphone amplifier is much better with respect to noise), or the line input which has a PGA for having 0 or 6 dB gain (for supporting 1 and 2 V (RMS) input). The PGA also provides gain control from 0 to 24 dB in steps of 3 dB. Remarks: * The input impedance of the PGA (line input) is 12 k, for the LNA this is 5 k * The LNA is standard equipped with a microphone power supply. Since this normally requires two extra pins, this feature will not be used inside the UDA1380. Instead, the microphone supply block is replaced by the VGA block.
The following Power-down modes and functional modes are supported: * Power-down mode in which the power consumption is very low (only leakage currents) In this mode there is no reference voltage at the line input * Line input mode, in which the PGA can be used * Microphone mode, in which the rest of the non-used PGAs and ADCs are powered-down * Mixed PGA and LNA mode: one line input and one microphone input. More information on the analog frond-end is given in Section 8.11.1.

LNA WITH VGA
8.2.3
APPLICATIONS WITH 2 V (RMS) INPUT
The LNA is equipped with a VGA. The function of the VGA is to have additional variable analog gain from 0 to 30 dB in steps of 2 dB. This provides more flexibility in the choice of the microphone.
For the line input it is preferable to have 0 dB and 6 dB gain settings in order to be able to apply both 1 and 2 V (RMS) input signals, using a series resistance. For this purpose a PGA is used which has 0 to 24 dB gain, in steps of 3 dB.

Product specification
Stereo audio coder-decoder for MD, CD and MP3
In applications in which a 2 V (RMS) input signal is used, a 12 k resistor must be used in series with the input of the ADC (see Fig.7). This forms a voltage divider together with the internal ADC resistor and ensures that the voltage, applied to the input of the IC, never exceeds 1 V (RMS). Using this application for a 2 V (RMS) input signal, the switch must be set to 0 dB. When a 1 V (RMS) input signal is applied to the ADC in the same application, the gain switch must be set to 6 dB. An overview of the maximum input voltages allowed against the presence of an external resistor and the setting of the gain switch is given in Table 2; the power supply voltage is assumed to be 3 V.

OVERLOAD DETECTION
The UDA1380 is equipped with an overload detector which can be read out from the L3-bus or I2C-bus interface. In practice the output is used to indicate whenever the output data, in either the output of the left or right channel, exceeds -1 dB (the actual figure is -1.16 dB) of the maximum possible digital swing. When this condition is detected the output bit OVERFLOW in the L3-bus register is forced to logic 1 for at least 512fs cycles (11.6 ms at fs = 44.1 kHz). This time-out is reset for each infringement. 8.3.2 VOLUME CONTROL

The decimator is equipped with a digital volume control. This volume control is separate for left and right and can be set with bits ML_DEC [7:0] and bits MR_DEC [7:0] via the L3-bus or I2C-bus interface. The range is from +24 dB to -63.5 dB and mutes in steps of 0.5 dB. 8.3.3 MUTE

The decimator is equipped with a dB-linear mute which mutes the signal in 256 steps of 0.5 dB. 8.3.4 AGC FUNCTION
The decimation filter is equipped with an AGC block. This function is intended, when enabled, to keep the output signal at a constant level. The AGC can be used for microphone applications in which the distance to the microphone is not always the same. The AGC can be enabled via an L3-bus or I2C-bus bit by setting the bit to logic 1. In that case it bypasses the digital volume control. Via the L3-bus or I2C-bus interface also some other settings of the AGC, like the attack and decay settings and the target level settings, can be made. Remark: The DC filter before the decimation filter must be enabled by setting the L3-bus or I2C-bus bit SKIP_DCFIL to logic 0 when AGC is in operation; otherwise the output will be disturbed by the DC offset added in the ADC.
8.3
Decimation filter (ADC)
The decimation from 128fs is performed in two stages. The sin x first stage realizes a ---------- characteristic with a decimation x factor of 16. The second stage consists of 3 half-band filters, each decimating by a factor 2. The filter characteristics are shown in Table 3.

UDA1380
The interpolation digital filter interpolates from 1 to 64fs or to 128fs, by cascading FIR filters, see Table 4. The interpolator is equipped with several sound features like volume control, mute, de-emphasis and tone control.

DIGITAL MUTE
In addition, there are basic sound features: * dB-linear volume control using 14-bit coefficients in steps of 0.25 dB: range 0 to -78 dB maximum suppression and - dB: applies to both master volume and mixing volume control * De-emphasis for 32, 44.1, 48 and 96 kHz for both channel 1 and 2 (selectable independently) * Treble, which is selectable gain for high frequencies (positive gain only), the edge frequency of the treble is fixed (depends on the sampling frequency). Can be set for left and right independently: - Two settings: fc = 1.5 kHz and fc = 3 kHz, assuming sampling frequency is 44.1 kHz - Both settings have 0 to 6 dB gain range in steps of 2 dB * Bass boost, which is selectable gain for low frequencies (positive gain only). The edge frequency of the bass boost is fixed and depends on the sampling frequency. Can be set for left and right independently: - Two settings: fc = 250 Hz and fc = 300 Hz, assuming sampling frequency is 44.1 kHz - First setting: 0 to 18 dB gain range in steps of 2 dB - Second setting: 0 to 24 dB gain range in steps of 2 dB. 8.5 Noise shaper

Muting the DAC will result in a cosine roll-off soft mute, using 4 x 32 = 128 samples in normal mode (or 3 ms at 44.1 kHz sampling frequency). The cosine roll-off curve is illustrated in Fig.8. These cosine roll-off functions are implemented for both the digital mixer and the master mute inside the DAC data path, see Section 8.8.

The noise shaper consists of two mono 3rd-order noise shapers and one time-multiplexed stereo 5th-order noise shaper. The order of the noise shaper can be chosen between 3rd-order (which runs at 128fs) and 5th-order (which runs at 64fs) via bit SEL_NS in the L3-bus or I2C-bus register. The preferable choice for the noise shaper order is: * 3rd-order noise shaper is preferred at low sampling frequencies, for instance between 8 and 32 kHz. This is for preventing out-of-band noise from the noise shaper to move into the audio band * 5th-order noise shaper is normally used at higher sampling frequencies, normally from 32 to 100 kHz. The noise shaper shifts in-band quantization noise to frequencies well above the audio band. This noise shaping technique enables high signal-to-noise ratios to be achieved. The noise shaper output is converted into an analog signal using an FSDAC.

8.6 8.6.1 FSDAC GENERAL INFORMATION 8.7 Headphone driver
UDA1380
The Filter-Stream Digital-to-Analog Converter (FSDAC) is a semi-digital reconstruction filter that converts the 1-bit data stream (running at either 64fs for the 5th-order noise shaper or 128fs for the 3rd-order noise shaper) of the noise shaper into an analog output voltage. The filter coefficients are implemented as current sources, and are summed at virtual ground of the output operational amplifier. In this way very high signal-to-noise performance and low clock jitter sensitivity are achieved. A post-filter is not needed due to the inherent filter function of the DAC. On-board amplifiers convert the FSDAC output current to an output voltage signal, capable of driving a line output. The output voltage of the FSDAC scales proportionally with the power supply voltage. Remark: When the FSDAC is powered-down, the output of the FSDAC becomes high impedance. 8.6.2 ANALOG MIXER INPUT
The UDA1380 is equipped with a headphone driver which can deliver 36 mW (at 3.0 V power supply) into a 16 load. The headphone driver does not need external DC decoupling capacitors because it can be DC coupled with respect to a special headphone output reference voltage. This saves two external capacitors (which is quite useful in a portable device). The headphone driver is equipped with short-circuit protection on all three operational amplifiers (left, right and the virtual ground). Each of the operational amplifiers has a signalling bit which becomes logic 1 in case the limiter is activated, for instance in case of a short-circuit. This means the microcontroller in the system can poll the L3-bus or I2C-bus register of the headphone driver and as soon as, and for as long as, the short-circuit detection bits are activated, the microcontroller can signal the user that something is wrong or power-down the headphone driver (for instance, for energy-saving purposes). Remark: To improve headphone channel separation performance, the distance between VREF(HP) and the micro speaker port must be minimized. 8.8 8.8.1 Digital and analog mixers (DAC) DIGITAL MIXER
The FSDAC has a mixer input, which makes it possible to mix an analog signal to the output signal of the FSDAC itself. In schematic form this is given in Fig.9. This mixer input can be used for instance for mixing-in a GSM signal or an FM signal directly to the line output. In the UDA1380, the mixer input is connected from the ADC line input via an AVC unit. Remark: Before the AVC unit can be used stand-alone, meaning without the digital part running, first the DAC part must be initialised in order to have the DAC output generating zero current. Otherwise the signal will be clipped.
The ADC output signal and digital input signal can be mixed without external DSP as shown in Fig.10. This mixer can be controlled via the microcontroller interface, and must only be enabled when the ADC and the DAC are running at the same frequency. In addition, the mixer output signal can also be applied to the I2S-bus output interface.

The analog mixer, which uses the mixer input of the FSDAC, can mix a signal into the FSDAC output signal via an AVC unit (see Fig.11). The mixer can be used to mix a signal into the FSDAC output signal and play it via the headphone driver without the complete coder-decoder running. The analog control range is 0 to -64.5 dB and mutes in steps of 1.5 dB, with a gain of 16.5 dB (so actually the range is from +16.5 dB to -48 dB plus mute).

8.9 Application modes 8.11 Power-down requirements
UDA1380
The operation mode can be set with pin SEL_L3_IIC, either to L3-bus mode (LOW) or to the I2C-bus mode (HIGH) as given in Table 5. For all features in microcontroller mode see Chapter 9. Table 5 Pin function in the selected mode PIN L3CLOCK/SCL L3MODE L3DATA/SDA L3-BUS MODE SEL_L3_IIC = L L3CLOCK L3MODE L3DATA MODE SEL_L3_IIC = H SCL A1 SDA I2C-BUS
The following blocks have power-down control via the L3-bus or I2C-bus interface: * Microphone amplifier (LNA) including its Single-Ended to Differential Converter (SDC) and VGA * ADC plus SDC and the PGA, for left and right separate * Bias generation circuit for the front-end and the FSDAC * Headphone driver * WSPLL * FSDAC. Clocks of the decimator, interpolator and the analog blocks have separate enable and disable controls.
Remark: In the I2C-bus mode there is a bit A1 which sets the LSB bit of the address of the UDA1380. In L3-bus mode this bit is not available, meaning the device has only one L3-bus device address. 8.10 Power-on reset
The UDA1380 has a dedicated pin RESET, which has a pull-down resistor. This way a Power-on reset circuit can be made with a capacitor and a resistor at the pin. The internal pull-down resistor cannot be used because of the 5 V tolerant nature of the pad. The pull-down resistor is shielded from the outside world by a transmission gate in order to support 5 V tolerance. The reset timing is determined by the external capacitor and resistor which are connected to the pin RESET, and the internal pull-down resistor. By the Power-on reset, all the digital sound processing features and the system controlling features are set to the default setting of the L3-bus and I2C-bus control modes. Remark: The reset time should be at least 1 s, and during the reset time the system clock should be running. In case the WSPLL is selected as the clock source, a clock must be connected to the SYSCLK input in order to have proper reset of the L3-bus or I2C-bus registers. This is because by default the clock source is set to SYSCLK.

FSDAC POWER CONTROL
The FSDAC block has power-on pins: one of which shuts down the DAC itself, but leaves the output still at VREF voltage (which is half the power supply). This function is set by the bit PON_DAC in the L3-bus or I2C-bus register. A second L3-bus or I2C-bus bit shuts down the complete bias circuit of the FSDAC, via bit PON_BIAS in the L3-bus or I2C-bus register. This bit PON_BIAS acts the same as given in Fig.12 for the analog front-end. 8.12 Plop prevention
the FSDAC or headphone driver can be powered-down. In case the FSDAC or headphone driver must be powered-up, first the analog part is switched on, then the digital part is demuted * When the ADC must be powered-down, a digital mute sequence must be applied. When the digital output signal is completely muted, the ADC can be powered-down. In case the ADC must be powered-up, first the analog part must be powered-up, then the digital part must be demuted * When there is a change of for example clock divider settings or clock source (selecting between SYSCLK and WSPLL clock), then also digital mute for that block (either decimator or interpolator) should be used. Remark: All items mentioned in Section 8.12 are not `hard-wired' implemented, but to be followed by the users as a guideline for plop prevention.
Plops are ticks and other strange sounds, that can occur when a part of a device is powered-up or powered-down, or when switching between modes is done. Some ways to prevent plops from occurring are: * When the FSDAC or headphone driver must be powered-down, first a digital mute is applied. After that 2002 Sep 16 19

8.13 Digital audio data input and output
UDA1380
The slave and master modes can be selected by the bit Serial Interface Mode (SIM) in the L3-bus or I2C-bus interface. 9 L3-BUS INTERFACE DESCRIPTION
The supported audio formats for the control modes are: * I2S-bus * MSB-justified * LSB-justified, 16 bits * LSB-justified, 18 bits * LSB-justified, 20 bits * LSB-justified, 24 bits (only for the output interface). The bit clock BCK can be up to 128fs, or in other words the BCK frequency is 128 times the WS frequency or less: fBCK 128fWS Remark: The WS edge must coincide with the negative edge of the BCK at all times, for proper operation of the digital I/O data interface. Figure 13 shows the interface signals. 8.13.1 DIGITAL AUDIO INPUT INTERFACE
The UDA1380 has an L3-bus microcontroller interface mode. Controllable system and digital sound processing features are: * Software reset * System clock frequency (selection between 256fs, 384fs, 512fs and 768fs clock divider settings) * Clock mode setting, for instance, which block runs at which clock, and clock enabling * Power control for the WSPLL * Data input and data output format control, for input and output independently including data source selection for the digital output interface * ADC features: - Digital mute - AGC enable and settings - Polarity control - Input line amplifier control (0 to 24 dB in steps of 3 dB) - DC filtering control - Digital gain control (+24 to -63 dB gain in steps of 0.5 dB) for left and right - Power control - VGA of the microphone input - Selection of line or microphone input * DAC and headphone driver features: - Power control FSDAC and headphone driver - Polarity control - Mixing control (only available when both decimator and interpolator run at the same speed). This includes the mixer volumes, mute and mixer position switch - De-emphasis control - Master volume and balance control - Flat/minimum/maximum settings for the bass boost and treble - Tone control: bass boost and treble - Master mute control - Headphone driver short-circuit protection status bits.
The digital audio input interface is slave only, meaning the system must provide the WSI and BCKI signals (next to the DATAI signal). Either the WSPLL locks onto the WSI signal and provides the internal clocks for the interpolator and the FSDAC, or a system clock must be applied which must be in frequency lock to the digital data input interface signals. 8.13.2 DIGITAL AUDIO OUTPUT INTERFACE
The digital audio output interface can be either master or slave. The data source for the data output can be selected from either the decimator (ADC front-end) or the digital mixer output. Remark: The digital mixer output is only valid if both the decimator and the interpolator run at the same clock: * In slave mode the signals on pins BCKO, WSO and SYSCLK must be applied from the application (signals must be in frequency lock) and the UDA1380 returns the DATAO signal from the decimator. The applied signal from pin BCKO can be for instance: 32fs, 48fs, 64fs, 96fs or 128fs * In master mode the SYSCLK signal must be applied from the system, but the UDA1380 returns with the BCKO, WSO and the DATAO signals. For the BCKO clock, there are 2 general rules: - When the SYSCLK is either 256fs or 512fs, the BCKO frequency is supposed to be 64fs - When the SYSCLK is either 384fs or 768fs, the BCKO signal should be 48fs. 2002 Sep 16 20

9.1 Introduction
UDA1380
The device address consists of one byte, which is split-up in two parts: * Bits 7 to 2 represent a 6-bit device address. In the UDA1380 this is 000001 * Bits 1 to 0 called Data Operation Mode, or DOM bits, represent the type of data transfer according to Table 6. 9.3 Slave address
The exchange of data and control information between the microcontroller and the UDA1380, is accomplished through a serial hardware interface comprising the following pins: L3DATA/SDA: microcontroller interface data line L3MODE: microcontroller interface mode line L3CLOCK/SCL: microcontroller interface clock line. Information transfer via the microcontroller bus is organized LSB first, and in accordance with the so called `L3' format, in which two different modes of operation can be distinguished: address mode and data transfer mode. Inside the microcontroller there is a hand-shake mechanism which takes care of proper data transfer from the microcontroller clock, to the destination clock domains. This means that when data is sent to the microcontroller interface, the system clock must be running. 9.2 Device addressing
The UDA1380 acts as a slave receiver or a slave transmitter. Therefore the signals L3CLOCK and L3MODE are only input signals. The data signal L3DATA is a bidirectional line. The UDA1380 slave address is shown in Table 7. Table 7 (MSB) 0 9.4 0 0 L3 slave address BIT 0 0 (LSB) 1
Register addressing
The device addressing mode is used to select a device for subsequent data transfer. The address mode is characterized by the signal on pin L3MODE being LOW and a burst of 8 pulses on pin L3CLOCK/SCL, accompanied by 8 bits. The fundamental timing is shown in Figs 14 and 15. Basically, two types of transfer can be defined: data transfer to the device, and data transfer from the device, as given in Table 6. Table 6 DOM BIT 1 0 0 1 1 Selection of data transfer DOM BIT 0 0 1 0 1 not used not used DATA and STATUS write or pre-read DATA and STATUS read TRANSFER
After sending the device address, including the flags (the DOM bits) whether information is read or written, one byte is sent with the destination register address using 7 bits, and one bit which signals whether information will be read or written. The fundamental timing for L3 is given in Fig.19. Basically there are three forms for register addressing: * Register addressing for L3 write: the first bit is a logic 0 indicating a write action to the destination register, followed by seven register address bits * Prepare read addressing: the first bit of the byte is logic 1; signalling data will be read from the register indicated * The read action itself: in this case the device returns a register address prior to sending data from that register. When the first bit of the byte is logic 0, the register address was valid, in case the first bit is a logic 1 the register address was invalid. Remarks: * Each time a new destination address needs to be written, the device address must be sent again * When addressing the device for the first time after power-up of the device, at least one L3 clock-cycle must be given to enable the L3 interface.
Table 6 shows that there are two types of data transfers: DATA and STATUS which can be read and written. Table 6 also shows that the DATA and STATUS read and write actions are combined.

9.5 Data write mode
UDA1380
For writing data to a device, four bytes must be sent. Figure 14 explains the data write mode in a signal diagram: * One byte with the device address, being `00000110', which is including the LSB code 01 for signalling write to the device * One byte starting with a logic 0 for signalling write, followed by 7 bits indicating the destination address * Two data bytes. The SYSCLK signal must be applied in data write mode. Table 8 L3 write data BIT L3 MODE Addressing mode Data transfer 1 Data transfer 2 Data transfer 3 Notes 1. First bit in time. 2. Last bit in time. 9.6 Data read mode * One byte with the device address including `11' is sent to the device, being 00000111. The `11' indicates that the device must write data to the microcontroller, then the microcontroller frees the L3DATA-bus so the UDA1380 can send the register address byte and its two-byte contents * The device now writes the requested register address on the bus, indicating whether the requested register was valid or not (logic 0 means valid, logic 1 means invalid) * The device writes the data from the requested register on the bus, being two bytes. The SYSCLK signal must be applied in data read mode. DATA TYPE device address register address MS data byte LS data byte 0(1) 0 0 D15 D7 1 1 A6 D14 D6 2 1 A5 D13 D5 3 0 A4 D12 D4 4 0 A3 D11 D3 5 0 A2 D10 D2 6 0 A1 D9 D1 7(2) 0 A0 D8 D0
For reading from the device, first a prepare-read must be done. After this, the device address is sent again. The device then returns with the register address, indicating whether the address was valid or not, and the data of the register. The following five steps explain this procedure, and an example of transmission is given in Fig.15. * One byte with the device address, being `00000110', which is including the LSB code 01 for signalling write to the address * One byte is sent with the register address from which it needs to be read. This byte starts with a logic 1, which indicates that there will be a read action from the register

10 I2C-BUS INTERFACE DESCRIPTION The UDA1380 supports I2C-bus microcontroller interface mode as well as the L3-bus mode; all features can be controlled by the microcontroller with the same register addresses as in the L3-bus mode. The exchange of data and control information between the microcontroller and the UDA1380 in I2C-bus mode is accomplished through a serial hardware interface comprising the following pins: L3CLOCK/SCL: microcontroller interface clock line, SCL L3MODE: sets the bit A1of the I2C-bus device address L3DATA/SDA: microcontroller interface data line, SDA. Figure 20 shows the clock and data timing of the I2C-bus transfer. 10.1 Addressing Table 12 I2C-bus register address (MSB) 0 A6 A5 BIT A4 A3 10.1.1 DEVICE ADDRESS (PIN A1)
UDA1380
The UDA1380 acts as either a slave receiver or a slave transmitter. Therefore the clock signal SCL is only an input signal. The data signal SDA is a bidirectional line. Table 11 shows the device address of the UDA1380. The device can be set to one of the two addresses by using bit A1 (which is pin L3MODE) to select. Table 11 I2C-bus device address (MSB) 0 10.1.2 0 1 1 BIT 0 A1 0 (LSB) R/W
REGISTER ADDRESS
Table 12 shows the register address format of the UDA1380. The register mapping in I2C-bus mode is the same as for the L3-bus interface.
Before any data is transmitted on the I2C-bus, the device which should respond is addressed first. The addressing is always done with the first byte transmitted after the start procedure. The UDA1380 device address is [A6 to A0] 00110(A1)0, with bit A1 as the address selection bit (two addresses possible).

Table 13 shows the I2C-bus configuration for a WRITE cycle. The WRITE cycle is used to write the data to the internal registers. The device and register addresses are one byte each, the setting data is always a pair of two bytes. The format of the WRITE cycle is as follows: 1. The microcontroller starts with a start condition (S). 2. The first byte (8 bits) contains the device address `00110A10' and a logic 0 (WRITE) for the bit R/W. 3. This is followed by an acknowledge (A) by the UDA1380. 4. After this the microcontroller writes the register address (ADDR) (8 bits) where the writing of the register content of the UDA1380 must start. 5. The UDA1380 acknowledges this register address (A). 6. The UDA1380 sends the two-bytes data with the Most Significant (MS) byte first, and then the Least Significant (LS) byte, each time acknowledged by the microcontroller. 7. The UDA1380 stops this cycle by generating an acknowledge (A). 8. Finally, the UDA1380 frees the I2C-bus and the microcontroller can generate a stop condition (P). Table 13 Master transmitter writes to UDA1380 registers in the I2C-bus mode INITIAL BYTE START S DEVICE ADDRESS 00110A10 R/W 0 A REGISTER ADDRESS ADDR A MS data byte MS1 A ACKNOWLEDGE FROM UDA1380 LS data byte LS1 A ...

Table 14 shows the I2C-bus configuration for a READ cycle. The READ cycle is used to read the data values from the internal registers. The format of the READ cycle is as follows: 1. The microcontroller starts with a start condition (S). 2. The first byte (8 bits) contains the device address `00110A10' and a logic 0 (WRITE) for the bit R/W. 3. This is followed by an acknowledge (A) by the UDA1380. 4. After this the microcontroller writes the register address (ADDR) where the reading of the register content of the UDA1380 must start. 5. The UDA1380 acknowledges this register address. 6. Then the microcontroller generates a repeated start (Sr). 7. Then the microcontroller generates the device address `00110A10' again, but this time followed by a logic 1 (READ) of the bit R/W. 8. The UDA1380 sends the two-bytes register contents with the Most Significant (MS) byte first, and then the Least Significant (LS) byte, each time acknowledged by the microcontroller. 9. The microcontroller stops this cycle by generating a negative acknowledge (NA). 10. Finally, the UDA1380 frees the I2C-bus and the microcontroller can generate a stop condition (P).

Using a 1-bit value, the power control settings of the bias circuits of the ADC, AVC and FSDAC can be set. When this bit is set to logic 0, the complete bias circuits of the analog front-end and the FSDAC are shut down. In this case, the reference voltage disappears from the input of the ADCs and LNA and the output of the FSDAC, this can cause plops, but saves power.

UDA1380
Line input select. A 1-bit value to set the multiplexer in the analog front-end to select between the LNA or the enable-in input for the left ADC. When this bit is logic 0: select line input. When this bit is logic 1: select LNA for the left ADC. Default value 0. Microphone input select. A 1-bit value to set the multiplexer at the ADC right channel output (on bit-stream level) which selects either the right channel data or the left channel data, in case only the microphone input is used. In that case the microphone signal can be applied to the decimator for both left and right. When this bit is logic 0: select right channel ADC. When this bit is logic 1: select left channel ADC (for instance for microphone input). Default value 0. DC filter bypass. A 1-bit value set to skip the DC filter which is just before the decimator. This DC filter is there to compensate for the DC offset added in the ADC (to remove idle tones from the audio band). This DC signal added (the DC dither) must not be amplified in order to prevent clipping. Therefore this DC offset is removed first. When this bit is logic 0: DC filter enabled. When this bit is logic 1: DC filter bypassed. Default value 1. DC filter enable. A 1-bit value set to enable the DC filter which is at the output of the decimator (running at 1fs). When this bit is logic 0: DC filter disabled. When this bit is logic 1: DC filter enabled. Default value 0.

21 SOLDERING 21.1 Introduction to soldering surface mount packages
UDA1380
If wave soldering is used the following conditions must be observed for optimal results: * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. * For packages with leads on two sides and a pitch (e): - larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 21.4 Manual soldering
This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. 21.2 Reflow soldering
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250 C. The top-surface temperature of the packages should preferable be kept below 220 C for thick/large packages, and below 235 C for small/thin packages. 21.3 Wave soldering
Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed.
Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.

1. For more detailed information on the BGA packages refer to the "(LF)BGA Application Note" (AN01026); order a copy from your Philips Semiconductors sales office. 2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 3. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 4. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 5. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 6. Wave soldering is suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
