| PMC-Sierra,Inc. PM5352 S/UNI(R)-155-STAR * Provides a generic 8-bit microprocessor interface for device control and register access. * Provides standard IEEE 1149.1 JTAG test port for boundary scan. * Performs flag sequence detection and insertion. * Performs CRC-CCITT and CRC-32 FCS generation and validation. * Performs byte stuffing and destuffing. * Checks for minimum and maximum packet lengths. * Provides a SATURN(R)-compatible Packet-over-SONET POS-PHY Level 2 Interface. 155 Mbit/s ATM and Packet-Over-SONET/SDH Physical Layer Device FEATURES * Single channel ATM and Packet-overSONET OC-3c (155 Mbit/s) PHY. * Provides on-chip clock and data recovery and clock synthesis. * Exceeds Bellcore-GR-253 jitter requirements. * Inserts and extracts ATM cells or POS packets into/from SONET SPE. * Filters and captures Automatic Protection Switch byes (K1 and K2) and detects APS byte failure. * Detects signal degrade and signal failure thresholds crossing alarms. * Captures and debounces synchronization status byte (S1). * Extracts and inserts the 16 or 64-byte section trace (J0) and path trace (J1) messages. * Extracts and inserts section/line data communication channels (DCC). * Provides circuitry to meet holdover, wander and long term stability. ATM * Implements the ATM Forum User Network Interface Specification. * Performs cell payload scrambling and descrambling. * Provides a UTOPIA Level 2-compliant system interface. * Provides synchronous cell transmit and receive FIFO buffers. PACKAGING * Low power, 3.3 V CMOS technology. * Packaged in a 304-pin Ball Grid Array (BGA) package. * Industrial temperature range (-40 to +85C). PACKET-OVER-SONET * Generic design that supports packetbased protocols like PPP, HDLC and Frame Relay. * Implements the PPP over SONET/ SDH specification according to RFC 2615 and 1662 of the IETF. APPLICATIONS * * * * DSLAM uplinks. Access concentrators. Layer 3 switches. ATM switches.
