PRELIMINARY  
XRT72L71  
DS3 ATM UNI/CLEAR CHANNEL FRAMER  
DECEMBER 2000  
REV. P1.0.5  
FEATURES  
GENERAL DESCRIPTION  
Compliant with UTOPIA Level 1 and 2 with 8 or 16  
Bit Interface Specification and supports UTOPIA  
Bus speeds of up to 50 MHz  
The XRT72L71 DS3 ATM User Network Interface  
(UNI)/Clear-Channel Framer is designed to function  
as either a DS3 ATM UNI or Clear channel framer.  
For ATM UNI applications, this device provides the  
ATM Physical Layer (Physical Medium Dependent  
and Transmission Convergence sub-layers) interface  
for both the public and private networks at DS3 rates.  
For Clear-Channel framer applications, this device  
supports the transmission and reception of “user da-  
ta” via the DS3 payload bits.  
Contains on-chip 16 cell FIFO in both the Transmit  
(TxFIFO) and Receive Directions (RxFIFO)  
Contains on-chip 54 byte Transmit OAM Cell buffer  
and a 108 byte Receive OAM cell buffer, for trans-  
mission, reception and processing of OAM cells.  
Supports PLCP or ATM Direct Mapping modes  
Supports M13 and C-Bit Parity Framing Formats  
Supports DS3 Clear Channel Framing Applications  
Includes PRBS Generator and Receiver  
The XRT72L71incorporates Receive, Transmit, Micro-  
processor Interface, Performance Monitor, Test and Di-  
agnostic and Line Interface Unit Scan Drive sections.  
Supports Local, Remote-Line, Cell, and PLCP  
Loop-backs  
APPLICATIONS  
Private User Network Interfaces  
ATM Switches  
Interfaces to 8 or 16 Bit wide Motorola and Intel µPs  
Low power 3.3V, 5V input tolerant, CMOS
