IC DESCRIPTION
PIN NAME FUNCTION INTERFACE
41 EW OUT An output terminal for E-W out.
42 Y/C VCC An Vcc terminal for Y/C circuit.
Supply 5V.
43 C-IN An input terminal for chroma signal.
(standard burst amplitude level 286mVp-p)
The Iow/High impedance status of this pin can
be read by bus to detect if S port is connceted
or not.
44 Cr IN Input terminals for Cb/Cr signals.
45 Cb IN This terminal is clamped by charging/
discharging the coupling capacitors
It is recommended that input impedance is
kept at or below 100 .
B.B.TINT (-/+ 12deg) / Sub color control are
available for Cb/Cr input signals.
46 VSM OUT The output terminal for veracity scanning
modulation (VSM).
The IIC Bus controls phase and Gain of VSM.
