This device provides a standard-interface intelligent switching solution ideal for a variety of access/edge, metro, and core applications. Typically, the VSC874 is used on a variety of line cards where it connects directly to media access controllers (MAC), framers, and network processing units (NPU). These line cards can then be interconnected using either a low-cost mesh without a switch device (‘direct mode’) or traditional central-switch architecture (‘fabric mode’). S P E C I F I C AT I O N S : SPI4.2 Interface that can Operate up to 16 Gbps 16 High Speed Serial Links that can Operate up to 40 Gbps Can Operate in Direct Mode or Fabric Mode SPI4 Interface can Operate in Framer Mode or Packet Mode Up to 16 Traffic Classes for Unicast and Multicast Data Provides SPI4 Burst Segmentation and Re-assembly Automatic Load Balancing Across one to Sixteen VSC882 Switch Chips Parallel and Two-wire Serial Interface Housed in a 672 BGA Package DIRECT MODE DIAGRAM: 10 Gbps Line Card VSC874 Queue Manager 10 Gbps Line Card VSC874 Queue Manager FABRIC MODE DIAGRAM: 10 Gbps Line Cards VSC874 Queue Manager Switch Card SPI4.2 SPI4.2 SPI4.2 2.5 Gbps or 5 Gbps Line Card CSIX CSIX 10 Gbps Line Card VSC874 Queue Manager SPI4.2 SPI4.2 VSC872 Queue Manager VSC874 Queue Manager VSC882 VSC882 Switch Switch Fabric Fabric xN 2.5 Gbps or 5 Gbps Line Cards CSIX CSIX Switch Card VSC882 VSC882 Switch Switch Fabric Fabric VSC872 Queue Manager xN CSIX CSIX VSC872 Queue Manager For more information on Vitesse Products visit the Vitesse web site at www.vitesse.com or contact Vitesse Sales at (800) VITESSE or sales@vitesse.com Vitesse, ASIC-Friendly, FibreTimer, TimeStream and Snoop Loop are trademarks of Vitesse Semiconductor Corporation.
