Microchip Technology Switchtec™ PFX Gen 5 Fanout PCIe® Switches

Microchip Technology Switchtec™ PFX Gen 5 Fanout PCIe® Switches support up to 100 lanes, 52 ports, 26 virtual switch partitions, and 48 Non-Transparent Bridges (NTBs). These switches provide hot- and surprise-plug controllers for each port, advanced error containment, comprehensive diagnostics and debug capabilities, and a wide breadth of I/O interfaces. Typical applications include data center equipment, defense and industrial servers, workstations, test equipment, video production and broadcasting equipment, cellular infrastructure, access networks, and metro networks.

Features

  • High-performance non-blocking Gen 5 switches:
    • 100-lane, 84-lane, 68-lane, 52-lane, 36-lane and 28-lane variants
    • Up to 48 NTBs assignable to any port
    • Logical Non-Transparent (NT) interconnect allows for larger topologies
