LA7642N
SECAM Format Color TV Chrominance Circuit
Overview
The LA7642N integrates the chrominance circuit for a
SECAM format TV in a single 16-pin DIP (300 mil)
package and provides an adjustment-free discriminator
circuit. In combination with the Sanyo LA7687, LA7688,
this IC can implement a multi-format color TV signal-
processing system.
