ORDERING INFORMATION

DESCRIPTION

Zarlink's dual channel VE8820 Tracking Battery VoicePort™

chipset implements a dual-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 chipset reduces system level cost, space, and power.

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

and dense, interface design without sacrificing features or

functionality. The programmable, feature rich VoicePort chipset

provides 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 with

wideband capability, flexible signal generator with tone

cadencing, caller ID generation and all BORSCHT functions.

These VoicePort chipset features are crucial for designing

cost-effective, full-featured Voice over Broadband solutions.
