s FUNCTION DESCRIPTION 1. Synchronous Mode 1) Horizontal synchronous There are two synchronous input terminals, first is pin-51 (SYNCIN1) and other is pin-49 (SYNCIN2). There are no difference, and selected by pin-50 (SYNCSW). The composite-synchronous/synchronous and Y signal input to pin-51/49 either. The input (pin-51/49) signal is separate by horizontal and vertical synchronous signal. The AFC loop consists of horizontal synchronous signal and 1/32 signal divided 32fH VCO output signal without any adjustment. The pin-56 (CSYNCOUT) is composite-synchronous signal output selected by pin-50, and open collector type. 2) Vertical synchronous The countdown circuit reset the data to use vertical synchronous signal and 32f H VCO output. This VD pulse is stable even if the weak-signal. 2. Color Signal Play Mode 1) ACC Circuit The chroma signal input to pin-14 (CIN), and detect the burst-signal through the HPF circuit, and controlled stable burst-signal feedback from demodulate output. When the pin-14 is GND level, the mode is composite input, and pin-19 (VIDEOIN) composite-video signal input to ACC circuit. 2) APC Circuit, and VCXO The burst signal level of chroma is constant by ACC circuit. The PLL circuit consists of VCXO and locked burst signal. The pin-13 (TINT) input DC voltage adjust the VCXO phase, and adjust the demodulate axis. When the pin-13 is GND, the mode is PAL, and only accepts analog RGB input. 3) Color Killer The chroma signal is output to demodulator when PLL locked, and the color killer is -42dB. 4) Color Circuit This circuit adjusts the color TINT. The pin-15 (COLOR) adjusts the chroma signal range from ACC circuit. This signal demodulator without burst signal by burst gate pulse (BGP). 5) DEMOD This DEMOD circuits demodulate color differential signal after the ACC circuit. The RGB signal consists of color differential and Y signal by matrix circuit, and input to Int./Ext. signal switches.

3. Y-signal Mode 1) TRAP The composite video signal input to pin-19 (VIDEOIN) without the chroma by TRAP circuit. The TPAP frequency is 3.58MHz, and not through when Y/C input mode. 2) Picture Circuit The Y/composite-signal input to pin-19 (VIDEOIN) without the synchronous signal. The pin-25 (PICTURE) adjusts the frequency characteristic around 2MHz and emphasizes the outline. The pin-25 level emphasizes outline depend on the DC voltage. The Y-signal output pin-22 (YOUT), and input to pin-24 (YINH) through the external second differential circuit. 4. INT./EXT. Signal Switch Mode The analog RGB signal (0.7VP-P typ.) input to pin-29, pin-31, and pin-33, and these signal clamps pedestal. The ext-signal select Y/C-signal or Int-signal by pin-26 (SW).
5. RGB SIGNAL MODE 1) Contrast The pin-27 (CONTRAST) adjusts the all of RGB signal, which is black-to-white range. 2) Amplifier This circuit is non-liner amplifier to adjust the RGB signal equal to the luminous characteristics. There is two-point adjustment for accurate correction. The pin-38 (VG1) adjusts low side, and the pin-39 (VG2) adjusts high side.
] Input Signal VG1 adjust VG2 adjust
3) Sub Circuit This circuit adjusts characteristics of B/R signal, and sub adjusts white-balance for the monitor. The pin-38 (SUBVG1R) and pin-36 (SUBVG2R) adjust low side with R-signal and high side with characteristics. The pin-39 (SUBVG1B) and pin-37 (SUBVG2B) adjust low side with B-signal and high side for characteristics. These terminal controls R-signal and B-signal separately. 4) Bright The pin-27 (CONTRAST) clamps the pedestal after the brightness adjustment (black to black).

5) Side Black The side-black circuit output black level, when the mode is black mask for wide picture. The RGB signal is black level when pin-42 (SIDEBLACK) input signal is low period only. 6) Output Amplifier The pin-41 (FRP) input to the timing pulse with inverting RGB output, and output the inverting RGB signal per every 1H. The RGB outputs are: FRP-High: Non-inverting output FRP-Low: Inverting output The center voltage is preset to half of Vcc.

6. Common Driver The LCD common invert RGB output, and the pin-4 (VCOMIN) input to the common driver signal (5VP-P). The pin-2 (VCOMAMP) adjusts the range, the pin-5 (VCOMCENT) adjusts the center voltage. The pin-7 (VCOMOUT) connect external discreet buffer, and feedback the buffer output for pin-6 (VCOMFB).
7. PWM Signal for Backlight The pin-60 (PWMOUT) output the PWM signal for LCD backlight, open collector type, and connect pull-up resistor. The pin-58 (PWMOUT) adjusts the PWM duty.
