NOTICE - The following device(s) are recommended alternatives:

The CPS-8, device number 80KSW0003, is a serial RapidIO switch whose functionality is central to routing packets for distribution among DSPs, processors, FPGAs, other switches, or any other S-RIO-based devices. It may also be used in serial RapidIO backplane switching. The CPS-8 supports serial RapidIO packet switching (unicast, multicast, and an optional broadcast) from any of its 8 input ports to any of its 8 output ports.


  • 8 bidirectional serial RapidIO (sRIO) lanes v 1.3
  • Port Speeds selectable: 3.125Gbps, 2.5Gbps, or 1.25Gbps
  • Provides I2C port for maintenance and error reporting
  • Master or Slave Operation
  • 20 Gbps of peak switching bandwidth
  • Non-blocking data flow architecture within each sRIO priority
  • Configurable for Cut Through or Store And Forward data flow
