TWO CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT
REV. 1.0.0
GENERAL DESCRIPTION
The XRT73L02M is a two-channel fully integrated Line Interface Unit (LIU) for E3/DS3/STS-1 applications. It incorporates independent Receivers, Transmitters in a single 100 pin TQFP package. The XRT73L02M can be configured to operate in either E3 (34.368 MHz), DS3 (44.736 MHz) or STS-1 (51.84 MHz) modes.The transmitter can be turned off or tri-stated for redundancy support and for conserving power. The XRT73L02M’s differential receiver provides high noise interference margin and is able to receive the data over 1000 feet of cable or with up to 12 dB of cable attenuation. The XRT73L02M provides both Serial Microprocessor Interface as well as Hardware mode for programming and control. The XRT73L02M supports local,remote and digital loop-backs. The XRT73L02M also contains an onboard Pseudo Random Binary Sequence (PRBS) generator and detector with the ability to insert and detect single bit error.
Provides low jitter clock outputs for either DS3,E3 or STS-1 rates. On-chip clock synthesizer provides the appropriate rate clock from a single 12.288 MHz Clock. Provides low jitter output clock.
TRANSMITTER:
Compliant with Bellcore GR-499, GR-253 and ANSI T1.102 Specification for transmit pulse Tri-state Transmit output capability for redundancy applications Transmitter can be turned on or off.
CONTROL AND DIAGNOSTICS:
5 wire Serial Microprocessor In...
