Package:
IDT82V2044E: 128-pin TQFP
DESCRIPTION:
The IDT82V2044E can be configured as a quad T1, quad E1 or quad
J1 Line Interface Unit. The IDT82V2044E performs clock/data recovery,
AMI/B8ZS/HDB3 line decoding and detects and reports the LOS condi-
tions. An integrated Adaptive Equalizer is available to increase the receive
sensitivity and enable programming of LOS levels. In transmit path, there
is an AMI/B8ZS/HDB3 encoder and Waveform Shaper. There is one Jitter
Attenuator for each channel, which can be placed in either the receive path
or the transmit path. The Jitter Attenuator can also be disabled. The
IDT82V2044E supports both Single Rail and Dual Rail system interfaces
and both serial and parallel control interfaces. To facilitate the network
maintenance, a PRBS/QRSS generation/detection circuit is integrated in
each channel, and different types of loopbacks can be set on a per channel
basis. Four different kinds of line terminating impedance, 75
, 100 , 110
and 120 are selectable on a per channel basis. The chip also provides
driver short-circuit protection and supports JTAG boundary scanning.
The IDT82V2044E can be used in SDH/SONET, LAN, WAN, Routers,
Wireless Base Stations, IADs, IMAs, IMAPs, Gateways, Frame Relay
Access Devices, CSU/DSU equipment, etc.
