P1.0.0 GENERAL DESCRIPTION The XRT73LC00A DS3/E3/STS-1 Line Interface Unit is a low power CMOS version of the XRT73L00A and consists of a line transmitter and receiver integrated on a single chip and is designed for DS3, E3 or SONET STS-1 applications. XRT73LC00A 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 XRT73LC00A 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.
