The Lattice CSI-2 to HDMI Reference Design for Lattice Avant™-AT showcases a full video path from a CSI-2 image sensor to HDMI output including sensor image processing in between the interfaces. The reference design uses a CSI-2 image sensor (IMX258) for sensing and Lattice CSI-2 D-PHY Receiver IP, and Lattice Byte-to-Pixel Converter IP to get the pixel data.
The reference design is delivered as a Lattice Radiant™ project which includes a full test environment to perform simulation and the necessary board control logic to run a live demonstration. Both simulation and demonstration systems are built around a core design referred as CSI-2 to HDMI core design in this document. The core design is built using the following Lattice IPs: CSI-2 D-PHY Rx, Byte-to-Pixel Converter, Debayer, Automatic White Balance, and Color Correction Matrix.
