Wireless Local Loop (WLL), PBX, ISDN NT1/TA FEATURES Complete BORSCHT function for 2 channels in a single VoicePort™ chipset — Integrated high voltage switching regulator controllers – Wide input voltage range (VSW =+3.3V to +35 V) – Switching power supply tracks line voltage minimizing active & ringing state power dissipation — Low power Idle and On-hook transmission states Worldwide Programmability — Two-wire AC impedance, Balance Impedance, Gain — DC feed voltage and current limit — Ringing frequency, voltage and current limit — 12 kHz and 16 kHz Metering — Programmable loop closure and ring trip thresholds Ringing — 5 REN — Up to 140-Vpk internal balanced sinusoidal or trapezoidal ringing with programmable DC offset — Unbalanced ringing for PBX trunk compatibility Powerful signal generator 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.
