Standalone & Embedded

Single Channel Wideband VoicePort™ Device

™

DESCRIPTION

The

implements a single-channel telephone line interface by

providing all the necessary voice interface functions from the

high voltage subscriber line to the µP/DSP digital interface.

This device reduces system level cost, space, and power by

achieving the highest level of voice integration possible.

Designers benefit by having a simple, cost effective, low power

and dense, interface design without sacrificing features or

functionality. The programmable, feature-rich VoicePort

devices provide a highly functional line interface which meets

the requirements of short and medium loop (up to 1500 Ohms

total) applications. Features include: high voltage switching

regulator, self-test, line test capabilities, integrated ringing (up

to 140-Vpk), worldwide software programmability, flexible

signal generator with tone cadencing, caller ID generation and

all BORSCHT functions. These VoicePort device features are

crucial for designing cost-effective, full-featured Voice over

Broadband solutions.
