CCIR-656 Video Format Timing
The diagrams in this section show transfer timing for pixel (YCrCb), line (horizontal), and frame (vertical) data in CCIR-656 video
mode. All output values assume a maximum pin loading of 50 pF. Note that in timing diagrams for CCIR-656 video, the label CTRL
indicates the VSYNC, HSYNC, and FIELD pins.
