Microchip Technology, Inc. PFX 52xG4 Gen 4 Fanout PCIe Switch PM40052

The Switchtec Gen 4 PM40052 PFX Fanout PCIe switch is a high reliability, high performance switch with significant power, cost, and board space supporting 52 lanes, 28 ports, and hot- and surprise-plug controllers for each port. PFX switches features advanced error containment, comprehensive diagnostics and debug capabilities, end-to-end dat integrity protection, high-quality, low power SERDES and secure boot image authentication. 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. Additional Features High-reliability PCIe with robust error containment, hot- and surprise-plug controllers per port, end-to-end data integrity protection, high-quality, low-power SERDES Significant power, cost and board space savings with support for 28 ports, 26 NTBs, and 14 virtual switch partitions and flexible *x1, x2, x4, x8, and x16 port bifurcation with no restrictions on configuring ports as either upstream or downstream, or on mapping ports to NTBs Comprehensive diagnostics and debugging Secure system solution with boot image authentication High-Performance Non-blocking Switches 52-lane variant Ports bifurcate to ×1*/×2/×4/×8/×16 lanes Up to 26 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 Diagnostics and Debug Real-time eye capture External loopback Errors, statistics, and performance counters Peripheral I/O Interfaces Up to 11 Two-Wire Interfaces (TWIs) with SMBus support Up to 4 SFF-8485-compliant SGPIO ports Up to 4 UARTs JTAG and EJTAG interface High-Speed I/O PCIe Gen 4 16 GT/s Supports OCuLink cabling, CEM ×16 slots, and other interfaces Manual PHY configuration for optical Power Management Active State Power Management (ASPM) Software-controlled power management ChipLink Diagnostic Tools Extensive debug, diagnostics, configuration, and analysis tools with an intuitive GUI The PM42100-KIT Switchtec Gen 4 PCIe switch evaluation kit is a device evaluation environment that supports multiple interfaces Evaluation Kit Access to configuration data, management capabilities, and signal integrity analysis tools (such as real-time eye capture) *x1 natively on four lanes
