●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 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.
