VoicePort™ chipset
DESCRIPTION
— Battery Feed, Over-voltage support, integrated Ringing,
line Supervision, Codec, Hybrid (2W/4W), Test
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
Integrated Power Management
— 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
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.
— 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
