SECAM-Format VCR
Chroma Signal-Processing Circuit
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.
Features
• All required filters, except for the bell filter,
incorporated on chip.
• Automatic adjustment of the bell filter f₀ parameter
• Built-in SECAM discrimination circuit
