21.3.1. Full-Raster to Streaming Converter Interfaces

The IP has two functional video interfaces, two clock domains, and two resets. The Intel FPGA streaming video protocol and the full-raster variant are standard interfaces to connect components that exchange video data.

All two input clocks are asynchronous from each other. Internally, the IP includes clock domain crossing circuits for both single bit and data bus signal cases, which safely allows data exchange between any of the two asynchronous clock domains. The IP also includes an embedded entity .sdc file, which provides all the necessary information to the Timing Analyzer. For system integration, when you instantiate the IP in a design, the only constraints required are:

  • Clock frequency constraints for the input video clock (vid_in_clock_clk)
  • Clock frequency constraints for the output video clock (vid_out_clock_clk)
