Monolithic Linear IC
LA71584M
Overview
For VHS VCR
Video Audio Signal Processor
(Y/C/A/HA 1chip)
The LA71584M is a signal processing IC for VHS VCRs. In addition to conventional video signal processing, it also
features normal audio processing, as well as recording/playback FM-EQ functions on-chip. Together with the CCD chip, it
is configured as a single package consisting of two chips.
This device eliminates the various adjustments that are usually performed by trimming inside the chip: by incorporating
automatic adjustments for the comb filter as well, it is completely adjustment-free. This has made it possible to reduce
significantly the number of externally attached components, simplify the design around the signal processing, and cut
production costs.
