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 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. 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
