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.
