Device Overview


The PM42100-KIT Switchtec Gen 4 PCIe Switch Evaluation Kit is used to evaluate the Switchtec Gen 4 PCIe family of switches.

The kit contains an evaluation board, cables and ChipLink Diagnostic Tools software. ChipLink is a convenient and easy-to-use Windows®/Mac®/Linux®-based GUI that provides access to all hardware functions and status information.

The kit operates with a PCIe® host and supports the connection of multiple host entities to multiple endpoint devices.

Additional Features
  • PCIe Interface
    • 1 ×16 edge connector for connection to a host
    • 1 ×16 slot connector for add-in cards
    • 16 ×4 PCIe OCuLink connectors to provide flexibility for a host or an end-point connection
  • PCIe Clock Interface
    • Common reference clock with or without Spread Spectrum Clocking (SSC)
    • Separate Reference Clock No SSC (SRNS)
    • Separate Reference Clock With Independent SSC (SRIS)
  • Serial Peripheral Interfaces (SPI)
    • 2 quad SPI buses
    • 128 Mb on-board SPI Flash for bootup and initialization
