LA72910V
Monolithic Linear IC
FM Modulator and
Demodulator IC
Overview
The LA72910V 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
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
