XRT59L91 - Single-Chip E1 Line Interface Unit

Description

The XRT59L91 is an optimized single-chip analog 3.3V E1 line interface unit (LIU) fabricated using low power CMOS technology.

The LIU IC consists of both a Transmitter and a Receiver function.

Features

  • l Complete E1 (CEPT) line interface unit (Transmitter and Receiver) Generates transmit output pulses that are compliant with the ITU-T G.703 Pulse Template for 2.048Mbps (E1) rates On-Chip Pulse Shaping for both 75W and 120W Line Drivers Receiver can either be transformer or capacitively-coupled to the line Detects and Clears LOS (Loss of Signal) per ITU-T G.775 Compliant with the ITU-T G.823 Jitter Tolerance Requirements Compliant with the ITU-T G.703 EOS Overvoltage protection requirements l.
