mote terminal equipment.  
GENERAL DESCRIPTION  
The XRT72L52, 2 Channel DS3/E3 Framer IC is de-  
signed to accept “User Data” from the Terminal  
Equipment and insert this data into the “payload” bit-  
The Microprocessor Interface is used to configure the  
Framer IC in different operating modes and monitor  
fields within an “outbound” DS3/E3 Data Stream. Fur- the performance of the Framer.  
ther, the Framer IC is also designed to receive an “in-

minal Equipment) and extract out the “User Data”.  
number of "Reset-upon-Read" and "Read-Only" reg-  
isters that contain cumulative and "one-second" sta-  
tistics that reflect the performance/health of the two  
The XRT72L52 DS3/E3 Framer device is designed to  
support full-duplex data flow between Terminal Equip- channels of the Framer IC/system.  
ment 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 E3-  
ITU-T G.832 Framing Formats.  
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.  
The XRT72L52 DS3/E3 Framer IC consists of two  
Transmit sections, two Receiver sections, two Perfor-  
mance Monitor Sections and a Microprocessor inter-  
face.  
• 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  
The Transmit Sections, include a Transmit Payload  
Data Input Interface, a Transmit Overhead data Input  
Interface Section, a Transmit HDLC Controller, a  
Transmit DS3/E3 Framer block and a Transmit LIU In-  
terface Block which permits the Terminal Equipment  
to transmit data to a remote terminal.  
APPLICATIONS  
• Network Interface Units  
• CSU/DSU Equipment.  
• PCM Test Equipment  
• Fiber Optic Terminals  
• DS3/E3 Frame Relay Equipment  
The Receive Sections, consist of a Receive LIU Inter-  
face, a Receive DS3/E3 Framer, a Receive HDLC  
Controller, a Receive Payload Data Output Interface,  
and a Receive Overhead Data Interface which allows
