Lattice Semiconductor Byte-to-Pixel Converter IP converts CSI-2/DSI standard-based video payload packets from D-PHYReceiver Module output to pixel format. In addition, Byte-to-Pixel Converter IP generates camera and video control signalsin the pixel domain based on CSI-2 or DSI synchronization packets.

Resource Utilization details are available in the IP Core User Guide.

Features

  • MIPI DSI compatible video formats
  • MIPI CSI-2 compatible video formats
  • 1-, 2-, or 4-lane inputs
  • 8-bit (gear 8) or 16-bit (gear 16) inputs per lane
  • 1, 2, or 4 output pixels per pixel clock cycle
