DL Input
The input terminal of 1H delayed

This is the power supply for the DL
circuit. Recommended supply voltage
is 9V.
PAL DL Input
A PAL chroma signal is led from the
TA8690AN, TA8691N. An internal
system switch selects this PAL signal
or SECAM signal according to the
system ID signal, and delivers to a
DL drive circuit.
DL Drive
The PAL/SECAM chroma signal
output (switched by internal system
switch) for a 1H delay line.

SECAM ID In
An input terminal of a PAL ID
signal. In case the DC voltage of
more than 2V is applied to this
terminal, the system switched to the
PAL mode.
When the SECAM ID circuit detects
the SECAM signal, the terminal pin
10 goes to low. So, in case that this
terminal is connected to the PAL
color control terminal, then the
system ID priority is set to SECAM.
