| PMC-Sierra,Inc. PM7346 S/UNI-QJET * Provides a SCI-PHY and 50 MHz UTOPIA Level 2 compliant 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-TSY000773, TA-TSY-000772, and E1 and E3 transmission systems according to the 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, PM4344 TQUAD, PM6344 EQUAD, and PM4314 QDSX T1 and E1 framer/line interface chips for T1 and E1 applications. * Provides programmable pseudorandom 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 of up to 1 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. SATURN Quad User Network Interface for J2/E3/T3 FEATURES * Single-chip quad 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-PHY0029.000. Each line can be individually configured for the desired rate. * Each quadrant provides on-chip DS3, E3 (G.751 and G.832), and J2 framers and can be configured to be used solely as a framer. When configured in framer mode, gapped transmit and receive clocks can be generated for interfaces that need access to only payload data bits. * Supports bypass of the internal framers and supports connections to an arbitrary rate external transmission system interface up to a maximum rate of 52 Mbit/s, which enables the S/UNIQJET to be used as a quad ATM cell delineator. * Implements ATM direct-cell mapping into T1, DS3, E1, E3, and J2 transmission systems according to ITU-T Recommendation G.804. * * * * * APPLICATIONS * ATM or Frame Relay Switches, Multiplexers, and Routers * SONET/SDH Mux DS3/E3 Tributary Interfaces * PDH Mux DS3/E3/J2 Line interfaces * DS3/E3/J2 Digital Cross-Connect Interfaces * DS3/E3/J2 PPP Internet Access Interfaces * DS3/E3/J2 Frame Relay Interfaces BLOCK DIAGRAM SIG T1: TPOHINS[4:1] SIG T2: TPOH/TDAT[4:1] SIG T3: TIOHM/TFP/TMFP[4:1] SIG T4: TICLK[4:1] SIG T5: TPOHCLK[4:1] SIG T6: TPOHFP/TFPO/TMFPO/TGAPCLK/TCELL[4:1] SIG T7: REF8KI TOHINS[4:1] TOH[4:1] TOHCLK[4:1] TOHFP[4:1] TRSTB SIG T1 SIG T2 SIG T3 SIG T4 SIG T5 SIG T6 SIG T7 TDO TMS TCK TDI DTCA[4:1] XBOC Receive HDLC TDPR Transmit HDLC Transmit O/H Access 1/2 TTB Transmit Trail Buffer IEEE P1149.1 JTAG Test Access Port TDAT[15:0] TPRTY TSOC TCA Line Encode PRGD BER Tester TPOS/TDATO[4:1] TNEG/TOHM[4:1] TCLK[4:1] TRAN J2, E3, or DS3 Transmit Framer SPLT Transmit ATM and PLCP Framer TXCP_50 Transmit Cell Processor TXFF Transmit 4-Cell FIFO System Interface RXCP_50 Receive Cell Processor RXFF Receive 4-Cell FIFO TADR[4:0] TENB TFCLK PHY_ADR[2:0] ATM8 RFCLK RENB RADR[4:0] RCA RBOC Receive FEAC RFDL Receive HDLC PMON Performance Monitor Receive O/H Access 1/2 TTB Receive Trail Buffer CPPM PLCP/cell Performance Monitor RSOC MPIF Microprocessor Interface RPRTY RDAT[15:0] DRCA[4:1] RCLK[4:1] RPOS/RDAT[4:1] RNEG/RLCV/ ROHM[4:1] Line Decode FRMR J2, E3, or DS3 Receive Framer ATMF/SPLR Receive ATM and PLCP Framer SIG R5 SIG R4 SIG R3 SIG R2 SIG R1 H[4:1] LK[4:1] FP[4:1] D[7:0] A[10:0] ALE RDB RSTB INTB SIG R1: FRMSTAT[4:1] SIG R2: RPOHCLK/RSCLK/RGAPCLK[4:1] CSB WRB PMC-1970823 (R4) 2001PMC-Sierra, Inc.
