| PM5345 Summary Information S/UNI-155 SATURN USER NETWORK INTERFACE * Monolithic SATURNTM SONET/SDH Asynchronous Transfer Mode User Network LAN Interface. * 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. FEATURES * Provides 4 cell deep FIFO buffers in both transmit and receive paths and provides interface circuitry for external FIFO expansion. * Expansion ports provides access to all overhead to allow external processing for full SONET/SDH Network-Node Interface (NNI) compliance. * Provides a generic 8-bit microprocessor bus interface for configuration, control and status monitoring. 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. * Low power, +5 Volt CMOS technology. * 160 pin plastic quad flat pack (PQFP) package. * 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. * Provides on-chip parallel-to-serial and serial-to-parallel conversion * ATM LAN interfaces for computers, workstations, switches and PCs APPLICATIONS * ATM public network switching system interfaces * B-ISDN User-Network Interfaces * Gigabit network interfaces * B-ISDN test equipment interfaces * Provides a standard 5-signal P1149.1 JTAG test port for boundary scan board test purposes.
