Switchtec PFX-L Fanout-Lite PCIe Gen3 Switch Family
PM8566, PM8565, PM8564, PM8563, PM8562, and PM8561
The Switchtec PFX-L Fanout-Lite PCIe Gen3 Switch Family is composed of
PCIe Base Specification 3.1-compliant switches supporting up to 96 lanes,
six virtual switch partitions, two non-transparent bridges (NTBs), six hot-plug
controllers, and comprehensive diagnostics and debug capabilities.
Typical applications for the PFX-L 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.
Features
High-Performance Non-Blocking Switches
• Up to 174 GB/s switching capacity
• 96-lane, 80-lane, 64-lane, 48-lane, 32-lane, and 24-lane variants
• Ports bifurcate to x4/x8/x16 lanes
• Up to two NTBs assignable to any port
• Logical non-transparent (NT) interconnect allows for larger topologies
• Supports 1+1 and N+1 failover mechanisms
• NT address translation using direct windows and multiple sub-windows
per BAR
• Supports multicast groups per port
Highlights
• Hot-plug controllers, end-to-end data integrity
protection, high-quality, and low-power fifth-
generation SERDES
• Comprehensive diagnostics and debugging:
PCIe generator and analyzer, per-port
performance and error counters, multiple
loopback modes, and real-time eye capture
• Up to 24 ports, two NTBs, and six virtual switch
partitions
• Flexible x4, x8, and x16 port bifurcation with
no restrictions on configuring ports as either
upstream or downstream, or on mapping ports
to NTBs
Error Containment
• Advanced Error Reporting (AER) on all ports
• Hot-plug controllers
• GPIOs configurable for different cable/connector standards
PCIe Interfaces
• Passive, managed, and optical cables
• SHPC-enabled slot and edge connectors
Diagnostics and Debug
• Transaction Layer Packet (TLP) generator for testing and debugging of links
and error handling
• Real-time eye capture
• Any-to-any port mirroring for debug purposes
• External loopback at PHY and TLP layers

• Up to two (master/slave) two-wire interfaces (TWIs) with SMBus support
• Up to 78 parallel GPIO pins
• 1 UART
• 1 QSPI with optional inline ECC
• JTAG and EJTAG interface
