Manufacturer: Exar (now MaxLinear)

Overview: .. áç JANUARY 2001 PRELIMINARY XRT72L54 REV. P1.1.2 FOUR CHANNEL DS3/E3 FRAMER IC WITH HDLC CONTROLLER.

General Description

The XRT72L54, 4 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 XRT72L54 DS3/E3 Framer device is designed to support full-duplex data flow between Terminal Equipment and an LIU (Line Interface Unit) IC.
