A serial interface protocol for data converters

The protocol is proposed and maintained by Teledyne-e2v, but it is not proprietary and everyone is free to adopt it to take advantage of its 87.5% data rate efficiency.

The ESIstream protocol is born from a strong need of the following combination:

    • Reduce data overhead on serial links.

    • Increase rate of useful data when linking high-speed data converters operating at GSPS sampling rate with a FPGA.

    • Simplify hardware implementation to be built on RF SiGe technologies.
