LA72912V
Overview
The LA72912V is a FM modulation and demodulation single-chip IC. Its adjustment free modulation/demodulation circuit
significantly reduces the number of peripheral circuits required and can contribute to lower production costs.
Functions
• ASK modulation and demodulation
• Video signal FM modulation and demodulation
• Video signal emphasis and de-emphasis function
• Drop-Out detecting function of Video FM signal
• FM mute function at Second-Call
