LA7451M

Two-Channel, Noise Reduction Processor

for 8-mm VCR PCM

Overview

The LA7451M is a two-channel, noise reduction processor

IC for 8-mm video recorder, pulse code modulation (PCM)

circuits.

The LA7451M incorporates two filters, on per channel,

comprising emphasis circuits, weighting compensators,

voltage-controlled amplifiers (VCA) and detectors. Filter

control circuitry sets the emphasis and weighting of each

filter.

The LA7451M operates from a 4.75V supply and is avail-

able in 30-pin MFPs.
