PM8576B-FEI [Microchip]

The Switchtec PM8576 PFX-I PCIe Gen 3 fanout switch is the industry's highest density, lowest power, high reliability PCIe Base Specification 3.1-compliant switch supporting 96 lanes, 24 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. PFX-I switches operate over an extended industrial temperature range of –40 °C ambient to 105 °C junction.
