DESCRIPTION

The IDT82V2041E can be configured as a single channel T1, E1 or J1

Line Interface Unit. The IDT82V2041E performs clock/data recovery, AMI/

B8ZS/HDB3 line decoding and detects and reports the LOS conditions. An

integratedAdaptiveEqualizerisavailabletoincreasethereceivesensitivity

and enable programming of LOS levels. In transmit path, there is an AMI/

B8ZS/HDB3 encoder and Waveform Shaper. There is one Jitter Attenua-

tor, which can be placed in either the receive path or the transmit path. The

Jitter Attenuator can also be disabled. The IDT82V2041E supports both

Single Rail and Dual Rail system interfaces. To facilitate the network main-

tenance, a PRBS/QRSS generation/detection circuit is integrated in the

chip, and different types of loopbacks can be set according to the applica-

tions. Four different kinds of line terminating impedance, 75 Ω, 100 Ω, 110

Ωand120Ωareselectable. Thechipalsoprovidesdrivershort-circuitpro-

tection and internal protection diode. The chip can be controlled by either

software or hardware.

The IDT82V2041E can be used in LAN, WAN, Routers, Wireless Base

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

CSU/DSU equipment, etc.
