General Description

The Teridian 73M1903 Analog Front End (AFE) IC includes fully differential hybrid driver outputs, which connect to the telephone line interface through a transformer-based DAA.

The receive pins are also fully differential for maximum flexibility and performance.

This arrangement allows for the design of a high performance hybrid circuit to improve signal to noise performance under low receive level conditions, and compatibility with any standard transformer intended for PSTN communications applications.

Overview

Simplifying System IntegrationTM.

Key Features

of the device include an input reference frequency circuit, which accepts a range of crystals from 9-27 MHz. It also accepts external reference clock values between 9-40 MHz generated by the host processor. In most.
