SECAM-Format VCR
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 adjustment­free circuit operation.
Features
• All required filters, except for the bell filter, incorporated on chip.
• Automatic adjustment of the bell filter f0parameter
• Built-in SECAM discrimination circuit
Functions
•4.3-MHz and 1.1-MHz band-pass filters, limiter, AGC (in playback mode)
• Divide-by-four circuit, 4× frequency multiplier circuit,
2.2-MHz band-pass filter
• Bell filter f0automatic adjustment circuit, SECAM discrimination circuit
• Sync gate
