Description

Amplifies and outputs the sync

portion of the video signal input

to FIL IN (Pin 69).

Sync separation circuit input.

Inputs the FIL OUT (Pin 2)

output signal via a capacitor.

Sync separation output.

Positive polarity output in open

collector format.

DA output.

Outputs the serial data

converted to DC voltage. The

current driving capacity is

±1.0mA (max.).

Connect a resistor between this

pin and GND1 to control the

internal LPF and trap

frequencies.

Connect a 33kΩ resistor

(tolerance ±2%, temperature

characteristics ±200ppm or less).

This pin is easily affected by

external noise, so make the

connection between the pin and

external resistor, and between

the GND side of the external

resistor and the GND1 pin as

close as possible.
