Product 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 20 Gbit/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 the PM5310 TBS devices from the PMC-Sierra CHESS(TM) product family and with the PM8610 SBS and the PM8611 SBSLITE.

FEATURES

  • Supports 32 STS-12 equivalent serial ports via 777.6 MHz, 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, 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 20 Gbit/s.
  • In TelecomBus, switches VT1.5, VT2, or STS-1 tributaries.
  • Supports switching of arbitrary non-standard 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 SBS or SBSLITE 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 a 32-bit microprocessor bus interface for configuration, control and status monitoring.
  • Low power 1.8 V / 3.3 V 0.18 µm CMOS technology.
  • Available in a high density 480-ball 35x35 mm UBGA.
  • -40 °C to +85 °C Industrial Temperature Operation.

Typical Applications include:

  • T1/E1 SONET/SDH Cross-connects.
  • T1/E1 SONET/SDH Add-Drop Multiplexers.
  • OC-48 Multiservice Access Multiplexers.
  • Channelized OC-12/OC-48 Any Service Any Port Switches.
  • Voice Gateways.
