The XRT73L00A DS3/E3/STS-1 Line Interface Unit is designed to be used in DS3, E3 or SONET STS-1 applications and consists of a line transmitter and receiver integrated on a single chip.
XRT73L00A can be configured to support the E3 (34.368 Mbps), DS3 (44.736 Mbps) or the SONET STS-1 (51.84 Mbps) rates.
In the transmit direction, the XRT73L00A encodes input data to either B3ZS (for DS3/STS-1 applications) or HDB3 (for E3 applications) format and converts the data into the appropriate pulse shapes for transmission over coaxial cable via a 1:1 transformer.
In the receive direction the XRT73L00A performs equalization on incoming signals, performs Clock Recovery, decodes data from either B3ZS or HDB3 for-mat, converts the receive data into TTL/CMOS for-mat, checks for LOS or LOL conditions and detects and declares the occurrence of line code violations. The XRT73L00A also contains a 4-Wire Microprocessor Serial Interface for accessing the on-chip Command registers.
