Summary Information  
S/UNI-155 SATURN USER NETWORK INTERFACE  
FEATURES  
Monolithic SATURN™ SONET/SDH  
Asynchronous Transfer Mode User  
Network LAN Interface.  
circuits and pseudo-ECL interfaces  
operating at the155 Mbit/s line rate.  
• Provides TTL compatible inputs and  
outputs and a pseudo-ECL  
compatible serial line side interface.  
• Provides 4 cell deep FIFO buffers in  
both transmit and receive paths and  
provides interface circuitry for  
external FIFO expansion.  
Implements the ATM transmission  
convergence (TC) sublayer for  
Broadband ISDN according to ANSI  
T1.646, ITU-T Recommendation  
I.432 and ATM Forum document  
"ATM User-Network Interface  
Specification", Version 3.1.  
• Low power, +5 Volt CMOS  
technology.  
• 160 pin plastic quad flat pack (PQFP)  
• Expansion ports provides access to  
all overhead to allow external  
processing for full SONET/SDH  
Network-Node Interface (NNI)  
compliance.  
package.  
APPLICATIONS  
Operates at 19.44 Mbytes/s,  
processing a duplex 8-bit or 16-bit  
data stream and mapping ATM cells  
into a SONET STS-3c or SDH STM-1  
compatible bit serial stream operating  
at 155 Mbit/s.  
• ATM LAN interfaces for computers,  
workstations, switches and PCs  
• Provides a generic 8-bit  
microprocessor bus interface for  
configuration, control and status  
monitoring.  
• ATM public network switching system  
interfaces  
• B-ISDN User-Network Interfaces  
• B-ISDN test equipment interfaces  
• Gigabit network interfaces  
• Provides a standard 5-signal  
P1149.1 JTAG test port for boundary  
scan board test purposes.  
Provides on-chip parallel-to-serial  
and serial-to-parallel conversion
