PIN NAME
output
Outputs oscillation waveform of
VCXO.
When 3.58NTSC killer-off this pin
voltage sets 3.2V.
When B / W or other systems
killer-off, this pin voltage sets 1.4V.
Outputs SCP (Sand Castle Pulse).
The output signal consists of clamp
pulse, horizontal blanking pulse, and
vertical blanking.
The minimum load resistance is 3kŸ.
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.
Outputs the Y signal that routed the
f
off with Bus.) and the Y delay line
circuit.
Outputs B-Y (U) or I signal.
It includes LPF that can remove
carrier.
