| PMC-Sierra,Inc. Preliminary PM5310 TBS TelecomBus Serializer for 2.5 Gbit/s Interconnect FEATURES * Encodes data from the Incoming parallel TelecomBus to a set of four working, a set of four protection, and a set of four auxiliary 777.6 Mbit/s LVDS serial TelecomBus links with extended 8B/10B-based encoding. * Decodes data from a set of four working, a set of four protection, or a set of four auxiliary 777.6 MHz LVDS serial links with extended 8B/10Bbased encoding to the Outgoing TelecomBus stream. * Provides capacity to carry an STS12/STM-4 stream in each LVDS serial TelecomBus link. Four links can be aggregated to form an STS-48c/STM16c stream. * Provides capacity to carry an STS12/STM-4 stream in each 8-bit bus of the parallel TelecomBus stream. Four 8-bit buses can be aggregated to carry an STS-48c/STM-16c stream. * Provides redundant working, protection and auxiliary transmit LVDS serial TelecomBus streams and * redundant receive LVDS serial TelecomBus streams for protection switching purposes. Provides independent time-slot interchange blocks on the Incoming and Outgoing parallel TelecomBus streams to allow arbitrary arrangement of time-slots at STS-1 granularity. Supports redundant working/protection time-space-time switch fabric. Supports through-traffic, drop-traffic and protection switching in UPSR, 2fibre BLSR and 4-fibre BLSR applications (when used with the PM5372 TSE). Uses extended 8B/10B-based line coding protocol on the serial links to provide transition density guarantee and DC balance and to offer a greater control character vocabulary than the standard 8B/10B protocol. Provides encoding of TelecomBus control signals at the multiplex section termination (MST) point, high-order path termination (HPT) point and loworder path termination (LPT) point. * Provides optional PRBS generation for each outgoing LVDS serial TelecomBus data link for off-line link verification. * Provides PRBS detection for each 8-bit bus on the Incoming parallel TelecomBus stream. * Provides PRBS detection for each incoming LVDS serial TelecomBus stream for off-line link verification. * Provides optional PRBS generator for each 8-bit bus on the outgoing parallel TelecomBus stream. * Provides in-service link verification by optionally overwriting the B1 and E1 byte of each constituent STS-1/STM-0 with a unique software programmable byte and its complement. * Provides pins to coordinate updating of the connection map of the time-slot interchange blocks in the local device, peer PM5310 TBS devices and companion PM5372 TSE devices. * Derives all internal timing from a single 77.76 MHz system clock. * * * * BLOCK DIAGRAM TCMP TJ0FP Transmit Working Disparity Encoder (TWDE #1 - #4) Transmit Protect Disparity Encoder (TPDE #1 - #4) Transmit Auxiliary Disparity Encoder (TADE #1 - #4) Transmit Working Serializer (TWPS #1 - #4) Transmit Protect Serializer (TPPS #1 - #4) Transmit Auxiliary Serializer (TAPS #1 - #4) Transmit Working LVDS Interface (TWLV #1 - #4) Transmit Protect LVDS Interface (TPLV #1 - #4) Transmit Auxiliary LVDS Interface (TALV #1 - #4) ID[4:1][7:0] IDP[4:1] IPL[4:1] IJ0J1[4:1] IPAIS[4:1] ITV5[4:1] ITPL[4:1] ITAIS[4:1] Incoming Data 8B/10B Encoder (ID8E #1 - #4) Incoming TelecomBus PRBS Processor (ITPP #1 - #4) Incoming PRBS 8B/10B Encoder (IP8E #1 - #4) Transmit Working Time-Slot Interchange (TWTI) Transmit Protect Time-Slot Interchange (TPTI) Transmit Auxiliary Time-Slot Interchange (TATI) TPWRK[4:1] TNWRK[4:1] TPPROT[4:1] TNPROT[4:1] TPAUX[4:1] TNAUX[4:1] Tx Ref SYSCLK Clock Synthesis Unit OD[4:1][7:0] ODP[4:1] OPL[4:1] OJ0J1[4:1] OPAIS[4:1] OTV5[4:1] OTPL[4:1] OTAIS[4:1] Outgoing TelecomBus PRBS Generator (OTPG #1 - #4) Receive Working TimeSlot Interchg (RWTI) Receive Protect Time-Slot Interchg (RPTI) Receive Auxiliary TimeSlot Interchg (RATI) Receive Working PRBS Monitor (RWPM #1 - #4) Receive Protect PRBS Monitor (RPPM #1 - #4) Receive Auxiliary PRBS Monitor (RAPM #1 - #4) Receive Working 8B/10B Decoder (RW8D #1 - #4) Receive Protect 8B/10B Decoder (RP8D #1 - #4) Receive Auxiliary 8B/10B Decoder (RA8D #1 - #4) Working Data Recovery Unit (WDRU #1 - #4) Protect Data Recovery Unit (PDRU #1 - #4) Auxiliary Data Recovery Unit (ADRU #1 - #4) Receive Working LVDS Interface (RWLV #1 - #4) Receive Protect LVDS Interface (RPLV #1 - #4) Receive Auxiliary LVDS Interface (RALV #1 - #4) RPWRK[4:1] RNWRK[4:1] RPPROT[4:1] RNPROT[4:1] RPAUX[4:1] RNAUX[4:1] Microprocessor Interface JTAG D [15:0] RSTB CSB WDB RDB A [11:0] ALE INTB TRSTB TCK TMS TDI RWSEL OCMP PMC-2000329 (P1) PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS' INTERNAL USE RJOFP TDO (c) Copyright PMC-Sierra, Inc. 2000 Preliminary PM5310 TBS TelecomBus Serializer for 2.5 Gbit/s Interconnect * Provides a generic 16-bit microprocessor bus interface for configuration, control, and status monitoring. * Implemented in 1.8/3.3 V 0.18 mm CMOS and packaged in a 352 ball UBGA. * Low power consumption of 4.2 W (maximum).
