73M1966B Datasheet Microdaa

Manufacturer: Teridian Semiconductor

Overview: 73M1866B/73M1966B MicroDAA™ with PCM Highway Simplifying System Integration™ DATA SHEET DS_1x66B_001 April.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The 73M1866B and 73M1966B use the Teridian patented Data Access Arrangement function (MicroDAA®) designed exclusively for ForeignExchange-Office (FXO) in Voice-over-IP (VoIP) applications.

These devices provide much of the circuitry required to connect PCM formatted voice channels to a PSTN via a two-wire twisted pair interface.

The package options provide the necessary functional programmability and protection required for easy worldwide homologation.

Key Features
