| Preliminary PM8620 NSE-20G 20G Narrowband Switch Element OVERVIEW The PM8620 NSE-20G is a monolithic CMOS integrated circuit that performs DS0 and above granularity Space (cross bar ) switching on 32 full duplex STS-12 streams. The device provides 20Gb/s (258,048 DS0s, 10,752 T1s/VT1.5s, 8064 E1s/VT2s, 384 DS3s/E3s) switching. The NSE-20G can be combined in applications with the PM5372 TSE and PM5310 TBS devices from the PMC CHESSTM product family and with the PM8610 SBS and PM8611 SBSLITE. * E1, VT1.5, VT2, DS3 and E3 tributaries. The NSE-20G can be used with the companion SBS devices to implement a switch fabric scaleable to 20Gb/s. In TelecomBus, switches VT1.5, VT2, or STS-1 tributaries. Supports switching of arbitrary nonstandard octet aggregates. Supports unicast, multicast, and broadcast for all switching modes. Supports full-duplex, in-band communication channels from the NSE to each SBS or SBSLITE device. These channels can be used to initialize and control the SBS's for fabric monitoring and maintenance. Supports "1+1" or "1:n" fabric redundancy in conjunction with the SBSTM or SBSLITETM devices. Supports two sets of switch settings and a controlled method of changing settings on STS-12 frame boundaries. PHYSICAL CHARACTERISTICS * Supports an IEEE P1149.1 JTAG test port. * Provides 32-bit microprocessor bus interface for configuration, control and status monitoring. * Low power 1.8 V / 3.3 V 0.18 m CMOS technology. * Available in a high density 480 ball 35 mm x 35 mm UBGA. * -40C to +85C Industrial temperature Operation. * * * * APPLICATIONS * T1/E1 SONET/SDH Cross-connects. * T1/E1 SONET/SDH Add-Drop Multiplexors. * OC-48 Multiservice Access Multiplexors. * Channelized OC-12/OC-48 Any Service Any Port Switches. * Voice Gateways. FEATURES * Supports 32 STS-12 equivalent serial ports via 777.6MHz, 8B/10B encoded LVDS links. Each port can be either Serial TelecomBus or Serial SBI336S. * In SBI mode, switches DS0 or NxDS0 for all T1 and E1 tributaries and aggregate columns for switching T1, * * BLOCK DIAGRAM RP[0] RN[0] LVDS Receiver, Data Recovery Unit, Receive Decoder and In-Band Link Controller * * * LVDS Transmitter, Transmit Serializer, Transmit Encoder and In-Band Link Controller TP[0] TN[0] * * * RP[31] RN[31] * * * LVDS Receiver, Data Recovery Unit, Receive Decoder and In-Band Link Controller * * * LVDS Transmitter, Transmit Serializer, Transmit Encoder and In-Band Link Controller * * * TP[31] TN[31] * * * DSO Crossbar Switch (DCB) RC1FP CMP SYSCLK Clock Synthesis Units (2) Tx ReF Microprocessor Interface JTAG PMC-2000171 (P4) PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS' INTERNAL USE (c) Copyright PMC-Sierra, Inc. 2001.
