High-availability Seamless Redundancy (HSR) Ethernet for Substation Automation Reference Design


Design files


This is a reference design for high-reliability, low-latency network communications for substation automation equipment in smart grid transmission and distribution networks. It supports the high-availability seamless redundancy (HSR) specification in the IEC62439 standard and precision-time protocol specification in IEEE1588. This design is a lower-cost alternative to FPGA approaches and provides the flexibility and performance to add features such as IEC61850 support without additional components.

  • Compliant to IEC62439-3 Clause 5 specification for HSR Ethernet communications
  • IEEE 1588 peer-to-peer transparent clock profile for network synchronization
  • Traffic filtering based on VLAN IDs, multicast/broadcast support and built-in storm prevention mechanism
  • Zero recovery time in case of network failure
    • Dual-ported
    • Full-duplex 100-Mbps Ethernet
  • Fully programmable and provides a platform for integration of additional applications
