DESCRIPTION:
The IDT82V2081 can be configured as a single channel T1, E1 or J1 Line
Interface Unit. In receive path, an Adaptive Equalizer is integrated to
remove the distortion introduced by the cable attenuation. The IDT82V2081
also performs clock/data recovery, AMI/B8ZS/HDB3 line decoding and
detects and reports the LOS conditions. In transmit path, there is an AMI/
B8ZS/HDB3 encoder, Waveform Shaper and LBOs. There is one Jitter
Attenuator, which can be placed in either the receive path or the transmit
path. The Jitter Attenuator can also be disabled. The IDT82V2081 supports
both Single Rail and Dual Rail system interfaces. To facilitate the network
maintenance, a PRBS/QRSS generation/detection circuit is integrated in
the chip, and different types of loopbacks can be set according to the appli-
cations. Four different kinds of line terminating impedance, 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 IDT82V2081 can be used in LAN, WAN, Routers, Wireless Base
Stations, IADs, IMAs, IMAPs, Gateways, Frame Relay Access Devices,
CSU/DSU equipment, etc.
