DESCRIPTION:
TheIDT82V2042EcanbeconfiguredasadualchannelT1,E1orJ1Line
Interface Unit. The IDT82V2042E performs clock/data recovery, AMI/
B8ZS/HDB3 line decoding and detects and reports the LOS conditions. An
integrated Adaptive Equalizeris availableto increasethe receive sensitivity
and enable programming of LOS levels. In transmit path, there is an AMI/
B8ZS/HDB3encoderandWaveformShaper.ThereisoneJitterAttenuator,
which can be placed in either the receive path or the transmit path. The Jitter
Attenuator can also be disabled. The IDT82V2042E supports both Single
RailandDualRailsysteminterfaces.Tofacilitatethenetworkmaintenance,
a PRBS/QRSS generation/detection circuit is integrated in the chip, and dif-
ferent types of loopbacks can be set according to the applications. Four dif-
ferent 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 internal protection diode and supports JTAG bound-
ary scanning. The chip can be controlled by either software or hardware.
The IDT82V2042E can be used in LAN, WAN, Routers, Wireless Base
Stations, IADs, IMAs, IMAPs, Gateways, Frame Relay Access Devices,
CSU/DSU equipment, etc.
