Microchip Switchtec™ PCIe® Switches

PCIe Gen3 fan-out switches provide up to 96 lanes with robust error containment

Microchip provides a comprehensive family of fan-out switches to enable the flexible implementation of high-speed signaling systems compliant with the PCIe Gen3 standard.

 

The Switchtec™ PFX/PFX-I PCIe Gen3 fan-out switch families implement multiple functions, including:

  • High-reliability PCIe 3.1-compliant switches supporting up to 96 lanes
  • 24 virtual switch partitions
  • 48 non-transparent bridges
  • Hot- and surprise-plug controllers for each port
  • Advanced error containment
  • Comprehensive diagnostics and debug capabilities

 

 

The PFX-I Gen3 PCIe switch supports the full feature set available on the PFX products, and operates over an extended temperature range, including a maximum junction temperature of 105°C, and a -40°C minimum ambient temperature.

 

The Switchtec PCIe Gen3 switches are available in multiple variants providing 96, 80, 64, 48, 32, or 24 lanes. The ports bifurcate from x2 to x16 lanes.

 

Error containment capabilities include advanced error reporting on all ports, downstream port containment on all downstream ports, and blocking of poisoned translation-layer packets. Completion time-out synthesis prevents incomplete non-posted transactions from causing an error state in an upstream host. 

 

GPIOs are configurable for different cable and connector standards.
