Description

When the IC is in the SECAM

identification mode, the 4.43 MHz

VCO oscillation waveform is output

from this pin only during the VBLK

period centering on DC = 1 V. If

current of 150 µA is led from this pin

during this identification mode, the IC

switches to the SECAM mode. In the

SECAM mode, DC = 5 V.

Crystal oscillator connection pins.

Connect the PAL/N and 4.43 MHz

crystals to Pin 2, the PAL/M crystal to

Pin 3, and the NTSC crystal to Pin 4.
