LA7688B

Overview

The LA7688B integrates VIF, SIF, video, chrominance, and deflection processing circuits for PAL/NTSC format TV sets on

a single chip and is provided in a 52-pin shrink package.

The VIF and SIF circuits achieve semi-adjustment-free operation, and are adjustment-free except for the VCO coil and the

RF AGC circuit. The chrominance circuit can be made adjustment-free by using the LC89950 1H delay line IC. All the signal

processing required for a multi-format color TV can be implemented by combining this product with the LA7642 SECAM

decoder IC.
