SINGLE CHANNEL E1 SHORT
HAUL LINE INTERFACE UNIT
DESCRIPTION
The IDT82V2051E is a single channel E1 Line Interface Unit. The
IDT82V2051E performs clock/data recovery, AMI/HDB3 line decoding and
detects and reports the LOS conditions. An integrated Adaptive Equalizer
is available to increase the receive sensitivity and enable programming of
LOS levels. In transmit path, there is an AMI/HDB3 encoder and Waveform
Shaper. There is one Jitter Attenuator, which can be placed in either the
receivepathorthetransmitpath.TheJitterAttenuatorcanalsobedisabled.
The IDT82V2051E supports both Single Rail and Dual Rail system inter-
faces. Tofacilitatethe network maintenance, a PRBS generation/detection
circuit is integrated in the chip, and different types of loopbacks can be set
according to the applications. Two different kinds of line terminating imped-
ance, 75
and 120 are selectable. The chip also provides driver short-
circuit protection and internal protection diode. The chip can be controlled
by either software or hardware.
The IDT82V2051E can be used in LAN, WAN, Routers, Wireless Base
Stations, IADs, IMAs, IMAPs, Gateways, Frame Relay Access Devices,
CSU/DSU equipment, etc.
