Triple-Rate SDI Reference Design


You can use the Arria® II GX Triple-Rate SDI reference design to accelerate the implementation of broadcast studio equipment such as video switcher-router, video server, and headend. This reference design demonstrates the Arria II GX capability on handling multi-rate uncompressed video with its built-in serializer/deserializer (SERDES) and clock data recovery (CDR).

Intel supplies the reference design as clear-text Verilog, except for the SDI MegaCore® function.
