SATURN User Network Interface for J2/E3/T3

PM7347

S/UNI-JET

FEATURES

• Single-chip ATM User Network Interface (UNI) operating at 44.736 Mbit/s, 34.368 Mbit/s, and 6.312 Mbit/s conforming to ATMF-95-1207R1, ATMF-94-0406R5, and AF-PHY-0029.000.

• Provides on-chip DS3, E3 (G.751 and G.832), and J2 framers. Can be configured for use solely as a framer. When configured in framer mode, gapped transmit and receive clocks can be generated for interfaces that need access only to payload data bits.

• Supports bypass of the internal framers and supports connections to an arbitrary-rate external transmission system interface up to a rate of 52 Mbit/s. This lets the S/UNI-JET be used as an ATM cell delineator.

• Implements ATM direct-cell mapping into T1, DS3, E1, E3, and J2 transmission systems according to ITU-T Recommendation G.804.

• Provides a SCI-PHY and 50 MHz UTOPIA Level 2 compatible 8- or 16-bit ATM-PHY Interface.

• Implements the Physical Layer Convergence Protocol (PLCP) for T1 and DS3 transmission systems according to the ATM Forum UNI Specification and ANSI TA-TSY-000773, TA-TSY-000772, and for E1 and E3 transmission systems according to ETSI 300-269 and ETSI 300-270.

• Implements the ATM physical layer for broadband ISDN according to ITU-T Recommendation I.432.

• Uses the PM4341 T1XC, PM6341 E1XC, PM4351 COMET, and framer/ line interface chips for T1 and E1 applications.

• Provides seamless interface to the VORTEX DSLAM chipset,

-ATLAS, and

S/UNI S/UNI-RCMP-200.

• Provides programmable pseudo-random test pattern generation, detection, and analysis features.

• Provides integral transmit and receive HDLC controllers with 128-byte FIFO depths.

• Provides performance monitoring counters suitable for accumulation periods up to one second.

• Provides an 8-bit microprocessor interface for configuration, control, and status monitoring.

• Provides a standard 5-signal P1149.1 JTAG test port for boundary scan board-test purposes.

• Low power 3.3 V CMOS technology with 5 V-tolerant inputs.

• Available in a high density 256-pin SBGA package (27 mm by 27 mm).

• Rated for industrial temperature operation.

APPLICATIONS

• DSLAM Uplinks

• Enterprise ATM/PPP Uplinks

• ATM or Frame Relay Switches, Multiplexers, and Routers

• DS3/E3/J2 PPP Internet Access Interfaces

• DS3/E3/J2 Frame Relay Interfaces
