Overview
The LA7975 is an IC that converts PAL SIF signals (5.5 MHz, 6 MHz, and 6.5 MHz) to 6 MHz. For the sake of high sound quality, this IC uses a unique mixer technique to supress interference from NICAM signals.

Functions
Mixer, amplifier, oscillator, oscillator mute

Features
Resistant to interference by NICAM signals
Small SIP-5 package
Wide range of usage voltage (5 V to 12 V)
