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.
