DESCRIPTION OF MAIN IC
S
CXA2069Q (IC200)
This is the Audio/Video switching IC which has 7 inputs
and 3 outputs. Input composition of this model
consists of NTSC main/sub signal through Tuner,
Composite video 1/2/3, S-VHS input 1/2, Component
1-S input and L/R input of Component 1/2. Output
consists of Y/C output of main/sub, Audio L/R output
and Monitor out.
3D DCF FOR MAIN PICTURE (IC202)
The Digital Comb Filter, seperates Y/C from Composite
(Tuner, Video) signal input in the main picture. This
IC outputs 2Vp-p (including Sync) Y signal and
560mVpp (color bar) C signal in 2Vp-p (including Sync)
Composite input.
LINE DCF FOR SUB PICTURE (IC201)
The Digital Comb Filter is a board to separate Y/C from
Composite (Tuner, Video) signal input in the sub
picture. This IC outputs 2Vp-p (including Sync) Y signal
and 560mVpp (color bar) C signal in 2Vp-p (including
Sync) Composite input.
TA 1270AF (IC504, 507)
These ICs, as the Video & Chroma Sync Processing ICs,
have the function of filtering Y, U, V Processing and
Sync in Y/C input. IC504 handles the sub picture and
IC507 handles the main picture.
