SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
DESCRIPTION
The M35052-XXXSP/FP is TV screen display control IC which can be used to display information such as number of channels, the date and messages and program schedules on the TV screen. In particular, owing to the built-in SYNC-SEP (synchronous separation) circuit, the synchronous correction circuit, the Decoder circuit, and to the Encoder circuit, external circuits can be decrease and character turbulence that occurs when superimposing can be reduced. The processor can conform to the EDS broadcast service and is suitable for AV systems such as VTRs, LDs, and so on. It is a silicon gate CMOS process and M35052-XXXSP is housed in a 20-pin shrink DIP package, M35052-XXXFP is housed in a 20-pin shrink SOP package. For M35052-001SP/FP that is a standard ROM version of M35052XXXSP/FP respectively, the character pattern is also mentioned.

When CS pin is "L", SIN serial data is taken in when SCK rises. Hysteresis input. Built-in pull-up resistor is included. This is the pin for serial input of data and addresses for the display control register and the display data memory. Also, serially outputs decode data according to the settings in the relevant registers (serial I/O). When "L", this pin resets the internal IC circuit. Hysteresis input. Includes built-in pull-up resistor. Please connect to +5V with the analog circuit power pin. This is the output pin for composite video signals. It outputs 2VP-P composite video signals. In superimpose mode, character output etc. is superimposed on the external composite video signals from CVIN. This is the input pin which determines the "white" character color level in the composite video signal. This is the input pin for external composite video signals. In superimpose mode, character output etc. is superimposed on these external composite video signals. Please connect to GND using circuit earthing pin. This is the output pin for encode data. It outputs three-value data. This is the pin for test. Connect this pin to GND during normal operation. This pin outputs the port output or BLNK1 (character background) signal. This pin outputs the port output or CO1(character) signal. Please connect to GND using circuit earthing pin (Analog side). This is the input pin for the sub-carrier frequency (fSC) for generating a synchronous signal. A frequency of 3.580MHz is needed for NTSC, and a frequency of 4.434MHz in needed for PAL and 3.576MHz is needed for M-PAL. Filter output pin 2. This is the input pin for external composite video signals. This pin inputs the external video signal clamped sync-chip to 1.5V, and internally carries out synchronous separation.

Supplemental explanation about display control register
(1) How to effect synchronous separation from composite video signals
Synchronous separation is effected as follows depending on the width of L-level of the vertical synchronous period. 1. Less than 8.4s ****** Not to be determined to be a vertical synchronous signal. 2. Equal to or higher than 8.4s but less than 15.6s ****** When two clocks continue, if take place, it is "L" period is determined to be a vertical synchronization signal. 3. Equal to or higher than 15.6s ****** It is "L" period is determined to be a vertical synchronous signal with no condition. The determination is made at the timing indicated by V in Fig.3 either in case 2 or in case 3.

Setting data in the second and subsequent lines, it is possible to set encode data to ten consecutive lines from those secified by registers EVP0 to EVP2. Similarly to encode line N specified by registers EVP0 through EVP2, extending encode lines to line N-1 and to line N+1, it is possible to read encode data more certainly. 23

CHARACTER FONT
Images are composed on a 12 ! 18 dot matrix, and characters can be linked vertically and horizontally with other characters to allow the display the continuous symbols. Character code "FF16" is so fixed as to be blank and to have no background, thus cannot assign a character font to this code.
(1) Border display (set by register BLK0, 1 (address F816))
12 dots
When the character extends to the top dot of the matrix, no border is left at the top.
18 dots
When the character extends to the bottom (18th) dot of the matrix, no border is left at the bottom.
Note: Hatching represents border.
(2) Cursor display (Border display)

Note 1 : Clamp sync chip to 1.50V. Note 2 : Set basic electric potential in consid eration of dynamic range of the transistor. Note 3 : External loop filter 1 constant is provisional valve.
In displaying color superimposition, enter into the OSCIN pin the fSC signal that phase-synchronizes with the color burst of the composite video signals (input to the CVIN pin). Note 7: In dealing with the internal synchronization, cut off external video signals outside the IC. The leakage of external input video signals can be avoided.

(2) Before setting registers at the starting of system, be __ to reset sure the M35052-XXXSP/FP by applying "L" level to the AC pin. (3) Power supply noise When power supply noise is generated, the internal oscillator circuit does not stabilize, whereby causing horizontal jitters across the picture display. Therefore, connect a bypass capacitor between the power supply and GND. (4) Synchronous correction action When switching channel or in the special playback mode (quick playback, rewinding, and so on) of VTR, effect of synchronous correction becomes strong, and distortion of a character is apt to occur because the continuity of video signal is suddenly switched. When the continuity of video signal is out of order, erasure of displayed characters is recommended in a extreme short time to raise the quality of displayed characters. (5) Notes on fSC signal input This IC amplifies the subcarrier frequency (fSC) signal (NTSC, MPAL system: 3.58MHz, PAL system: 4.43MHz) input to the OSCIN pin (17-pin) and generates the composite video signal internally. The amplified fSC signal can be destabilized in the following cases. a) When the fSC signal is outside of recommended operating conditions. b) When the waveform of the fSC signal is distorted. c) When DC level in the fSC waveform fluctuates. When the amplified signal is unstable, the composite video signal generated inside the IC is also unstable in terms of synchronization with the subcarrier and phase. Consequently, this results in color flicker and lost synchronization when the composite video signal is generated. Make note of the fact that this may prevent a stable blue background from being formed. (6) Forbidding to stop entering the fSC signal This IC doesn't properly work if the fSC signal is not entered into the OSCIN pin (pin 17), so do not stop the fSC signal so as to work the IC. To stop the IC, turn the display off (set 0 in the register DSPON (address F816).) (7) Forbidding to set data during the period in which the internal oscillation circuit stabilizes a) To start entering the fSC signal when its input is stopped. b) To start oscillating the oscillation circuit for display when its oscillation is stopped. (to assign "1" to the register STOP1 (address F816) when it is assigned "0", or the like.) c) To turn on the internal bias when it is turned off. (to assign "1" to the register LEVEL1 (address F816) when it is assigned "0".) There can be instances in which data are not properly set in the registers until the internal oscillation circuit stabilizes, so follow the steps in sequence as given below. 1) Set "0" in the register DSPON (address F816). (the display is turned off) 2) Effect the settings a), b), and c) given above.
3) Wait 20 ms (the period necessary for the internal oscillation circuit to stabilize) before entering data. 4) Set necessary data in other registers, and make the display RAM ready.
