XRT72L52 - TWO CHANNEL DS3/E3 FRAMER IC

General Description

The XRT72L52, 2 Channel DS3/E3 Framer IC is designed to accept “User Data” from the Terminal Equipment and insert this data into the “payload” bitfields within an “outbound” DS3/E3 Data Stream.

Key Features

  • Transmits, Receives and Processes data in the DS3-C-bit Parity, DS3-M13, E3-ITU-T G.751 and E3-ITU-T G.832 Framing Formats.
  • 2 Channel HDLC Controller - Tx and Rx.
  • Interfaces to all Popular Microprocessors.
  • Integrated Framer Performance Monitor.
  • Available in a 160 Pin PQFP package.
  • 3.3V Power Supply with 5V Tolerant I/O.
  • Operating Temperature -40°C to +85°C.

www.DataSheet4U.com áç JANUARY 2001 PRELIMINARY XRT72L52 REV. P1.1.3 TWO CHANNEL DS3/E3 FRAMER IC WITH HDLC CONTROLLER GENERAL DESCRIPTION The XRT72L52, 2 Channel DS3/E3 Framer IC is designed to accept “User Data” from the Terminal Equipment and insert this data into the “payload” bitfields within an “outbound” DS3/E3 Data Stream. Further, the Framer IC is also designed to receive an “inbound” DS3/E3 Data Stream (from the Remote Terminal Equipment) and extract out the “User Data”. The XRT72L52 DS3/E3 Framer device is designed to support full-duplex data flow between Terminal Equipment and an LIU (Line Interface Unit) IC. The Framer Device will transmit, receive and process data in the DS3-C-bit Parity, DS3-M13, E3-ITU-T G.751 and E3ITU-T G.832 Framing Formats.
