DESCRIPTION:
Interface Unit. In receive path, an Adaptive Equalizer is integrated to
remove the distortion introduced by the cable attenuation. The IDT82V2082
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 IDT82V2082 supports
both Single Rail and Dual Rail system interfaces. To facilitate the network
maintenance, a PRBS/QRSS generation/detection circuit is integrated in
.
