FEATURES  
Single chip quad ATM User Network Interface operating at 1.544 Mbit/s or  
2.048 Mbit/s.  
Implements the ATM Forum User Network Interface Specification V3.1 for  
DS1 and E1 transmission rates.  
Implements the ATM physical layer for Broadband ISDN according to ITU-T  
Recommendation I.432.  
Implements the direct cell mapping into DS1 or E1 transmission systems  
according to ITU-T Recommendation G.804.  
Implements (with an external framer device) the direct cell mapping into J2  
(6.312 Mbit/s) transmission systems according to ITU-T Recommendation  
G.804.  
Integrates a quad full-featured T1/E1 framer/transmitter for terminating four  
duplex 1.544 Mbit/s DS-1 signals or four duplex 2.048 Mbit/s E1 signals.  
Integrates a quad ATM cell processor for mapping ATM cells into T1, E1 and  
other arbitrary rate streams using HEC (Header Check Sequence Error  
Correction) cell delineation.  
Provides Saturn Compatible Interface (SCI-PHYTM) FIFO buffers in both  
transmit and receive paths with parity support and Utopia Level 2 compatible  
multi-PHY control signals.  
Software compatible with the PM4341A T1XC, PM6341 E1XC, and PM7345  
S/UNI-PDH.  
Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board  
test purposes.  
Provides a generic 8-bit microprocessor bus interface for configuration,  
control, and status monitoring.  
Low power, +5V, CMOS technology  
128 pin rectangular (14mm x 20mm) PQFP package.
