DESCRIPTION:
TheIDT82V2081canbeconfiguredasasinglechannelT1,E1orJ1Line
Interface Unit. In receive path, an Adaptive Equalizer is integrated to
removethedistortionintroducedbythecableattenuation.TheIDT82V2081
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
, 100 ,
110
and 120 are selectable. The chip also provides driver short-circuit
protectionandinternalprotectiondiode.Thechipcanbecontrolledbyeither
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.
- Active edge of transmit clock (TCLK) and receive clock (RCLK)
- Active level of transmit data (TDATA) and receive data (RDATA)
- Receiver or transmitter power down
- High impedance setting for line drivers
- PRBS (Pseudo Random Bit Sequence) generation and detection
with 215-1 PRBS polynomials for E1
- QRSS (Quasi Random Sequence Signals) generation and detection
with 220-1 QRSS polynomials for T1/J1
- 16-bit BPV (Bipolar Pulse Violation) /Excess Zero/PRBS or QRSS
error counter
- Analog loopback, Digital loopback, Remote loopback and Inband
loopback
Cable attenuation indication
