when pin 18 is “L” and pin 38 is
“H.” RGB standby mode when
pins 18 and 38 are “H.” CS-REC
mode when pin 18 is “H” and pin
38 is “L.”

Output pin for regulator voltage in
IC. S/ N improvement measures
recommended by inserting a
capacitor of about 470
μ
F between
this pin and GND. The amplifier
reference voltage on the SW side
is based on the regulator voltage
of pin 20 and that on the driver
side is based on the regulator
voltage of pin 40.

Pin to control gain of composite
and Y signals when AGC-AMP is
used. To suppress crosstalk, it is
recommended to insert a noise
suppressing capacitor near the
pin between the pin and GND.

Pin 36 can be used for detection
of no-signal because LPF is
applied. Pin 37 is for detection of
the weak electric field. Pin 37 can
be changed to V.SYNC-OUT.
