iES-12 – Integrated Ethernet Switch


  • 12 Tri-Speed Ports with Layer 2/3 Management
  • Switch Connected Programmable FPGA for Packet Level Data Processing
  • HDLC/Chapter 7 Encoded PCM Output
  • Internal GPS Receiver & IRIG-A/B/G Time Code Generator
  • 4 IRIG DC/1PPS Outputs & 4 IRIG AM Outputs
  • Up to 4 IEEE-1588v2 Clocks w/ Grand Master Capability
  • Up to 16 Programmable Discrete Inputs/Outputs

The integrated Ethernet Switch (iES-12), is a rugged 12 port layer 2/3 managed gigabit Ethernet switch with end node timing and discrete signal capabilities for demanding test instrumentation environments on airborne, shipboard or mobile ground vehicles.

A user programmable FPGA with soft CPU(s) tied directly into the switch provides packet extraction/inspection/insertion capabilities. Programmable or data driven discrete outputs can be used to control end node devices on or off the network as well as feedback into the iES-12 from discrete inputs.

With multiple time sources and outputs the iES-12 provides end node device IRIG time signals. iES-12 contains a high time accuracy internal GPS receiver and a hardware based IEEE-1588v2 time engine both able to drive the internal IRIG-A/B/G Time Code Generator (TCG) for time outputs.

The integrated board stack architecture and front panel allow for user specific functions and connector interfaces to be implemented without compromising system architecture or integrity.
