DESCRIPTION:

The IDT82V2082 can be configured as a dual channel T1, E1 or J1 Line

Interface Unit. In receive path, an Adaptive Equalizer is integrated to

removethedistortionintroducedbythecableattenuation.TheIDT82V2082

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. TheJitterAttenuatorcanalsobedisabled. TheIDT82V2082supports

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 Ω,100 Ω,

110 Ω and 120 Ω are selectable on a per channel basis. The chip also pro-

vides driver short-circuit protection and internal protection diode and sup-

ports JTAG boundary scanning. The chip can be controlled by either

software or hardware.

The IDT82V2082 can be used in LAN, WAN, Routers, Wireless Base

Stations, IADs, IMAs, IMAPs, Gateways, Frame Relay Access Devices,

CSU/DSU equipment, etc.
