Zarlink's dual channel VE8820 Tracking Battery VoicePortT chipset implements a dual-channel telephone line interface by providing all the necessary voice interface functions from the high voltage subscriber line to the #P/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.
