Parallel Data Interface (Camera Interface)
Clock for the parallel data from the input video data
Vertical sync to indicate the start of new frame for the display
Horizontal sync to indicate the start of new line for the display
Data Enable for the camera data input
18-bit parallel input data for the display
Display Interface
Pixel clock used to drive the display panel
Vertical sync signal, indicating the beginning of a new frame
Horizontal sync signal, indicating the beginning of a new line
When high, this signal indicates that the pixel is tagged and an application can
calculate CRC externally on this pixel.
Data Enable. Qualifies the data output
Red, green and blue data output.
