FUNCTION DESCRIPTION Synchronous Mode Horizontal synchronous There synchronous input terminals, first pin-51 (SYNCIN1) other pin-49 (SYNCIN2). There difference, selected pin-50 (SYNCSW). signal input pin-51/49 either. input (pin-51/49) signal separate horizontal vertical synchronous signal. loop consists horizontal synchronous signal 1/32 signal divided 32fH output signal without adjustment. pin-56 (CSYNCOUT) composite-synchronous signal output selected pin-50, open collector type. Vertical synchronous countdown circuit reset data vertical synchronous signal output. This pulse stable even weak-signal. Color Signal Play Mode Circuit chroma signal input pin-14 (CIN), detect burst-signal through circuit, controlled stable burst-signal feedback from demodulate output. When pin-14 level, mode composite input, pin-19 (VIDEOIN) composite-video signal input circuit. Circuit, VCXO burst signal level chroma constant circuit. circuit consists VCXO locked burst signal. pin-13 (TINT) input voltage adjust VCXO phase, adjust demodulate axis. When pin-13 GND, mode PAL, only accepts analog input. Color Killer chroma signal output demodulator when locked, color killer -42dB. Color Circuit This circuit adjusts color TINT. pin-15 (COLOR) adjusts chroma signal range from circuit. This signal demodulator without burst signal burst gate pulse (BGP). DEMOD This DEMOD circuits demodulate color differential signal after circuit. signal consists color differential signal matrix circuit, input Int./Ext. signal switches.

Y-signal Mode TRAP composite video signal input pin-19 (VIDEOIN) without chroma TRAP circuit. TPAP frequency 3.58MHz, through when input mode. Picture Circuit Y/composite-signal input pin-19 (VIDEOIN) without synchronous signal. pin-25 (PICTURE) adjusts frequency characteristic around 2MHz emphasizes outline. pin-25 level emphasizes outline depend voltage. Y-signal output pin-22 (YOUT), input pin-24 (YINH) through external second differential circuit. INT./EXT. Signal Switch Mode analog signal (0.7VP-P typ.) input pin-29, pin-31, pin-33, these signal clamps pedestal. ext-signal select Y/C-signal Int-signal pin-26 (SW).
SIGNAL MODE Contrast pin-27 (CONTRAST) adjusts signal, which black-to-white range. Amplifier This circuit non-liner amplifier adjust signal equal luminous characteristics. There two-point adjustment accurate correction. pin-38 (VG1) adjusts side, pin-39 (VG2) adjusts high side.
Input Signal adjust adjust
Circuit This circuit adjusts characteristics signal, adjusts white-balance monitor. pin-38 (SUBVG1R) pin-36 (SUBVG2R) adjust side with R-signal high side with characteristics. pin-39 (SUBVG1B) pin-37 (SUBVG2B) adjust side with B-signal high side characteristics. These terminal controls R-signal B-signal separately. Bright pin-27 (CONTRAST) clamps pedestal after brightness adjustment (black black).
