PM50068B1-FEI [Microchip]

The Switchtec PFX 68xG5 Fanout PCIe® Switch is high-reliability PCIe switch supporting  68 lanes, 36 ports and hot- and surprise-plug controllers for each port.  This switch features advanced error containment and comprehensive diagnostics and debug capabilities, a wide breadth of I/O interfaces and an integrated MIPS processor.

Typical applications for the PFX family include data center equipment, defense and industrial servers, workstations, test equipment, video production and broadcasting equipment, cellular infrastructure, access networks, metro networks and core networking.
