PCI Express I/O Interconnect Switches

PLX Technology — February 2007

PCI Express I/O Interconnect Switches

PCI Express (PCIe) Switches ranging from 5 to 48 lanes and 3 to 9 ports

  • Low latency at 110ns
  • Native Cut-Thru architecture
  • Max payload size of 1 KB
  • Weighted Round Robin Port Arbitration, 3 Standard Hot-Plug Controllers
  • and an I2C interface
  • Suitable for high-end applications requiring fan-out
  • PEX 8532, PEX 8524, and PEX 8516 switches support Non-Transparent Bridging and a Standard Hot-Plug Controller on each por
  • The Non-Transparent Bridging allows for dual-host support in fail-over applications used in storage systems, communications platforms, or intelligent adapter cards
  • The PEX 8518, PEX 8517, and PEX 8508 offer high-performance fan-out for lower-end applications
  • Low latency among 16- and 8-lane switches at 150ns
  • Cut-Thru architecture, Non-Transparent Bridging, and a Standard Hot-Plug Controller on every port
  • Suitable, these switches are ideal for NICs, HBAs, AdvancedMCs, Notebook Docking Stations, and Intelligent I/O modules
  • PEX 8509 and PEX 8505 offer an equal number of lanes and ports
  • PEX 8548 48 lanes, 9 ports, Typical Power 4.9 W
  • PEX 8547 48 lanes, 3 ports, Typical Power 4.9 WPEX 8533 32 lanes, 6 ports, Typical Power 3.3 W
  • PEX 8525 24 lanes, 5 ports, Typical Power 2.6 W
  • PEX 8532 32 lanes, 8 ports, Typical Power 5.7 W
  • PEX 8524 24 lanes, 6 ports, Typical Power 3.9 W
  • PEX 8516 16 lanes, 4 ports, Typical Power 3.2 W
  • PEX 8518 16 lanes, 5 ports, Typical Power 2.6 W
  • PEX 8517 16 lanes, 4 ports, Typical Power 2.6 W
  • PEX 8508 8 lanes, 5 ports, Typical Power 1.6 W
  • PEX 8509 8 lanes, 8 ports, Typical Power 1.5 W
  • PEX 8505 5 lanes, 5 ports, Typical Power 1.5 W
