SCP output
Outputs SCP (Sand Castle Pulse).
The output signal consists of clamp
pulse, horizontal blanking pulse, and
vertical blanking.
The minimum load resistance is 3k
.

SECAM
control
The input / output pin that is used to
control the SECAM demodulation IC.
When current stronger than 250μA
flows from this pin, that is recognized
as SECAM.

TRAP (TRAP can be turned on or
off with Bus.) and the Y delay line
circuit.
5
U / Q output
Outputs B-Y (U) or I signal.
It includes LPF that can remove
carrier.
