Single Rail CODEC

This vMerSsMio7n7: 1A7u-0g1. /10929/803

Previous version: Nov. 1996

GENERAL DESCRIPTION

The MSM7717 is a single-channel CODEC CMOS IC for voice signals ranging from 300 to 3400

Hz with filters for A/D and D/A conversion.

Designed especially for a single-power supply and low-power applications, the device is

optimized for ISDN terminals and telephone terminals in digital wireless systems.

The device uses the same transmission clocks as those used in the MSM7508B and MSM7509B.

The analog output, which can drive a 1.2 kW load, can directly drive a handset receiver

differentially.

FEATURES

• Single power supply: 2.7 V to 3.8 V
