SECAM-Format VCR

Chroma Signal-Processing Circuit

LA7337

Overview

The LA7337 is an IC that implements SECAM-format

VCR signal processing in a single chip. It incorporates

band-pass filters and a SECAM discrimination circuit on

chip and features automatic adjustment of the bell filter for

a reduced number of external components and adjustment-

free circuit operation.
