IDT82V2058 OCTAL E1 SHORT HAUL LINE INTERFACE UNIT

INDUSTRIAL TEMPERATURE RANGES

DESCRIPTION:

The IDT82V2058 is a single chip, 8-channel E1 short haul PCM

transceiver with a reference clock of 2.048MHz. It contains 8 transmit-

ters and 8 receivers.

Both receivers and transmitters can be programmed to work either

in single rail mode or dual rail mode. AMI or HDB3 encoder/decoder

is selectable in single rail mode. Pre-encoded transmit data in NRZ

format can be accepted when the device is configured in dual rail

mode. The receivers perform clock and data recovery by using

integrated digital phase-locked loop. As an option, the raw sliced data

(no retiming) can be output on the receive data pins. Transmit

equalization is implemented with low-impedance output drivers that

provide shaped waveforms to the transformer, guaranteeing template

conformance.

A jitter attenuator is integrated in the IDT82V2058 and can be

switched into either the transmit path or the receive path. The jitter at-

tenuation performance meets ETSI CTR12/13, ITU G.736, G.742, and

G.823 specifications.

The IDT82V2058 offers hardware control mode and software con-

trol mode. Software control mode works with either serial host interface

or parallel host interface. The latter works via an Intel/Motorola com-

patible 8-bit parallel interface for both multiplexed or non-

multiplexed applications. Hardware control mode uses

multiplexed pins to select different operation mode when host in-

terface is not available to the device.

The IDT82V2058 also provides loopback testing functions and

JTAG boundary scan testing functions. As the monitoring function is

integrated, IDT82V2058 can be configured as a 7-channel transceiver

with non-intrusive protected monitoring points.

The IDT82V2058 can be used for SDH/SONET multiplexers, cen-

tral office or PBX, digital access cross connects, digital radio base sta-

tions, remote wireless modules and microwave transmission systems.
