3 Channel E3/ds3/sts-1 Line Interfce Unit

The XRT73L03 is a 3-Channel, E3/DS3/STS-1 Line Interface Unit designed for E3, DS3 or SONET STS-1 applications and consists of three independent line transmitters and receivers integrated on a single chip. Each channel of the XRT73L03 CAN be configured to support the E3 (34.368 Mbps), DS3 (44.736 Mbps) or the SONET STS-1 (51.84 Mbps) rates. Each channel CAN be configured to operate in a mode/data rate that is independent of the other channels. In the transmit direction, each channel in the XRT73L03 encodes input data to either B3ZS or HDB3 format and converts the data into the appropri- ate pulse shapes for transmission over coaxial cable via a 1:1 transformer. In the receive direction, the XRT73L03 CAN perform Equalization on incoming signals, perform Clock Re- covery, decode data from either B3ZS or HDB3 for- mat, convert the receive data into TTL/CMOS format, check for LOS or LOL conditions and detect and de- clare the occurrence of Line Code Violations.
