Luminance output pin for the S pin
The output amplitude (output current
for 1 LSB) of the DAC is specified
using an external resistor, and this pin
controls the value of the current flow-
ing per bit.
When there is HIGH input at the signal
input pin which switches to and from
the low power consumption mode, this
turns off the output from the YOUT
and COUT pins.
Input pin for the reference clock in the
Video-CD mode
Reset input pin which initializes the
system. The system is reset when
this goes LOW.
Selects the F characteristic of the
Y-FILTER.
