Reliable data transfer is critical in many applications to ensure data movement through the system.

Redundant links:

  • Prevent critical system shut down
  • Key where time sensitive data can cause a safety issue or financial loss.
  • Help ensure transient data which cannot be stored or retransmitted is not lost, such as in high-speed data acquisition

Redundancy may be required over a cable, backplane or a printed circuit board, and some systems may require multiple levels of redundancy. The below diagram illustrates a typical application, showing a “2×2” redundant switch plus line card solution.


  • Support industry communication standards
  • Protocol independent data payloads
  • Strong signal integrity ensuring reliable data transfer
  • Support Forward Error Correction (FEC) to significantly reduce the number of missed packets and data retransmission requests.
  • Package and power options supporting line card, daughter card and module applications are integral to system power and heat issues


The MoSys MSH420 device is the best fit for redundant systems.

  • Supports critical industry standards, such as:
    • IEEE and OIF 10G, 25G, 40G and 100G standards
    • Protocol independent payload supports Datacom, Telecom, Storage applications
    • Forward Error Correction (FEC) payload support allows direct connection to 25G and 100G optical standards requiring RS-FEC (e.g. SR/SR4, CWDM, PSM4)
  • Independent PLLs per lane support different data rates within a single device
  • Signal integrity is key to ensuring reliable transfer of data
    • MoSys self-adapting RX equalizers for ease of connection
    • Reduce board design and bring-up time by eliminating per-lane “tuning”
  • Reduces the number of missed packets or data retransmission
  • Package and power options for line card, daughter card, and module applications
    • Board power is always an issue in a system. The MSH420 has the lowest power/performance ratio
  • Up to 5, bidirectional, Redundant Link Mode channels in a single MSH420 device
  • Cost/performance must be considered in any system design:
    • Some devices in volume at less than $50 each


  • Adherence to industry standards for interoperability with other available industry devices
  • Strong signal integrity and package/power options support cable, backplane, printed circuit boards and module level solutions.
  • Redundant links and FEC can significantly reduce data loss and retransmission, while improving system uptime and availability


  • High-reliability control environments
  • Data loss prevention in critical systems
  • High-availability systems
  • Financial transaction execution
