Description

The XRT83L314 is a fully integrated 14-channel longhaul and short-haul line interface unit (LIU) that operates from a single 3.3V power supply. Using internal termination, the LIU provides one bill of materials to operate in T1, E1, or J1 mode independently on a per channel basis with minimum external ponents.

Key Features

  • Receive monitor mode handles 0 to 29dB resistive attenuation (flat loss) along with 0 to 6dB cable loss for both T1 and E1
  • Fully integrated 14-Channel short haul and long haul transceivers for T1/J1 (1.544MHz) and E1 (2.048MHz) applications
  • Receiver line attenuation indication output in 1dB steps
  • Loss of signal (RLOS) according to ITU-T G.775/ ETS300233 (E1) and ANSI T1.403 (T1/J1)
  • Programmable receive slicer threshold (45%, 50%, 55%, or 68%) for improved receiver interference immunity
  • Power down on a per channel basis with
  • Five pre-programmed transmit pulse settings for T1 short haul applications
  • Programmable data stream muting upon RLOS detection
  • On-Chip HDB3/B8ZS encoder/decoder with an internal 16-bit LCV counter for each channel
  • Arbitrary pulse generator for T1 and E1 modes
