MICROCHIP PM40028B1-F3EI

The Switchtec PFX Gen 4 Fanout PCIe Switch Family comprises high-reliability PCIe switches supporting up to 100 lanes, 52 ports, 26 virtual switch partitions, 48 non-transparent bridges (NTBs), hot- and surprise-plug controllers for each port, advanced error containment and comprehensive diagnostics and debug capabilities, a wide breadth of I/O interfaces and an integrated MIPS processor.

• High-Performance Non-Blocking Gen 4 Switches:
  • 100-lane, 84-lane, 68-lane, 52-lane, 36-lane and 28-lane variants
  • Ports bifurcate from to x1/x2/x4/x8/x16 lanes
  • Up to 48 NTBs assignable to any port
  • Logical non-transparent (NT) interconnect allows for larger topologies
  • Supports 1+1 and N+1 failover mechanisms
• DMA Controller:
  • High-performance, ultra-low latency DMA engine
• Error Containment:
  • Advanced Error Reporting (AER) on all ports
  • Downstream Port Containment (DPC) on all downstream ports
  • Completion Timeout Synthesis (CTS) to prevent an error state in an upstream host due to incomplete non-posted transactions
  • Hot- and surprise-plug controllers per port
  • GPIOs configurable for different cable/connector standards
• PCIe Interfaces:
  • Passive, managed and optical cables
  • SFF-8644, SFF-8643, SFF-8639, OCuLink and other connectors
