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.

In the receive direction the XRT73LC00A performs equalization on incoming signals, performs Clock Recovery,decodes data from either B3ZS or HDB3 format,converts the receive data into TTL/CMOS format, checks for LOS or LOL conditions and detects and declares the occurrence of line code violations.

The XRT73LC00A also contains a 4-Wire Microprocessor Serial Interface for accessing the on-chip Command registers.
