PMC-Sierra,Inc. PM5346 S/UNI-155-LITE 155 Mb/s SATURN User Network Interface for LANs FEATURES * Low-cost, monolithic SATURN SONET/SDH ATM User Network Interface (UNI). * Implements the ATM transmission convergence (TC) sublayer according to ATM Forum specifications using the SONET/SDH 155.52 Mbit/s STS- 3c/ STM-1, and 51.84 Mbit/s STS-1 formats. * Supports ATM-Forum mid-range PHY and PMC-Sierra UNI-PHYTM subrates at 25.92 and 12.96 Mbit/s. * Supports UTP-5 or STP twisted pair wiring interface devices and optical driver and receiver modules for fiber optic cable interfaces. * Includes on-chip, Bellcore-compliant clock recovery and clock synthesis. * Operates in timing master or timing slave (loop timed) modes. (R) * Frames to SONET/SDH framing bytes (A1 and A2), processes the section and line Bit Interleaved Parity (B1 and B2) and the Far-End Block Error (Z2) bytes. * Interprets the H1, H2, and H3 payload pointer bytes. * Processes the SONET path overhead BIP-8 (B3), signal label (C2), and path status (G1) bytes. * Inserts and extracts ATM payloads using ATM cell delineation. * Provides on-chip FIFO buffers in both transmit and receive paths. * Provides on-chip support for Generic Flow Control (GFC) and XOFF flow control. * Provides a synchronous, 8-bit, plusparity SATURN-Compliant Interface for PHYsical layer devices (SCI-PHYTM) bus operating at 33 MHz. * Compatible with ATM Forum UTOPIA interface format, with support for multiPHY applications. * Provides a generic 8-bit microprocessor bus interface for configuration, control, and monitoring. * Provides TTL-compatible inputs and outputs and differential PECL inputs. * Low power, +5 V CMOS technology. * Packaged in a 128-pin 14 mm by 20 mm Plastic Quad Flat Pack (PQFP) with 0.5 mm lead pitch. APPLICATIONS * 155.52, 51.84, 25.92 and 12.96 Mbit/s Twisted Pair or Optical ATM LANs * Workstations and Personal Computer NIC Cards * Switches, Hubs, and Router Port Cards * SONET- or SDH-Compliant ATM UNIs BLOCK DIAGRAM RATE0 RATE1 TGFC TBYP TFPO TCLK TCP XOFF ATP2 Line Side System Side TRCLK+ TRCLKTXC+ TXCTXD+ TXD- Clock Generator Parallel to Serial Driver Transmit Framer and Overhead Processor Transmit ATM Cell Processor Transmit ATM Cell FIFO TSOC TXPRTY TDAT[7:0] TCA TWRENB TFCLK RXDO+ RXD+ RXDRXDORRCLK+ RRCLKALOS+ ALOSClock Recovery Microprocessor Interface Data Recovery Receive Framer and Overhead Processor Receive ATM Cell Processor RSOC RXPRTY RDAT[7:0] Receive ATM Cell FIFO RCA RRDENB RFCLK TSEN Serial to Parallel RALM RBYP ATP1 LF+ LFLFO PMC-930908 (R9) PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS' INTERNAL USE 1998 PMC-Sierra, Inc.
