U2860B-M - Dual-Channel FM Sound Demodulator

General Description

The U2860B-M is a dual-channel FM sound demodulator realized with Atmel ’s advanced bipolar process.

All TV FM standards, from 4.5 MHz up to 6.5 MHz (standard M, B/G, I, D/K) can be processed with high performance.

The circuit is alignment-free and has a minimum number of external components.

Key Features

  • Two Alignment-free PLL FM Demodulators, Automatic Lock-in on the Received Sound Carrier Frequency.
  • Mono and Dual Channel.
