XRT73L02M Datasheet

Two Channel E3/ds3/sts-1 Line Interface Unit

Manufacturer: Exar (now MaxLinear)

XRT73L02M Overview

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.

XRT73L02M Key Features

  • On chip Clock and Data Recovery circuit for high input jitter tolerance
  • Meets the jitter tolerance requirements as specified in ITU-T G.823_1993 for E3 and Telcordia GR-499CORE for DS3

XRT73L02M Applications

  • 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
  • pliant with Bellcore GR-499, GR-253 and ANSI T1.102 Specification for transmit pulse
  • Tri-state Transmit output capability for redundancy applications
