FUNCTION
Composite video signal or Y signal
input pin. Input via the clamp
capacitor.
V
CHROMA processing block. Connect
5 V (Typ.).
UV / CbCr demodulation switch.
CbCr demodulation is effective for
NTSC only.
Outputs crystal oscillator fsc.
The pin voltage goes high only when
3.58NTSC is received.
Outputs PAL / SECAM / NTSC
identification result.
Adjust to DC and connect output to
1H DL IC.
