UHD Serial Digital Interface (UHD-SDI)

The UHD Serial Digital Interface (UHD-SDI), is widely used in broadcast applications for the transport of uncompressed digital video streams up to 4K resolutions over coax cable. Xilinx offers two solutions for implementing SDI interfaces on Xilinx devices.

UHD-SDI subsystems are newer than the SMPTE UHD-SDI core and supports US+ devices and additionally gives users option to map SDI native video to AXI4-Stream Video interface, and adds an AXI4-lite control interface for use with a processor such as Microblaze or Arm subsystem. For all new designs, Xilinx recommends using SDI subsystems.

The UHD SDI LogiCORE IP can be implemented in Xilinx 7-series and UltraScale FPGAs. Users can implement one to many 4K processing channels including capture and display on a single FPGA using UHD-SDI IP and Video processing cores from Xilinx and its partners.  The UHD SDI LogiCORE IP is designed based on applicable SMPTE standards. LogiCORE version of SDI IPs are in maintenance mode and are not recommended for new designs. Xilinx recommends using SDI subsystems for all new designs.
