TERMINAL FUNCTIONS
PIN
No.
PIN NAME
FUNCTION
1 f_sc 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
2 SCP output pulse, horizontal blanking pulse, and
vertical blanking.
The minimum load resistance is 3kΩ.

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.
