Multiplexed Philips Video Timing
The diagrams in this section show transfer timing for pixel (YCrCb) data in Multiplexed Philips video mode. For line (horizontal)
and frame (vertical) data transfer timing, see Figure 29. All output values assume a maximum pin loading of 50 pF. Note that in
timing diagrams for Multiplexed Philips video, the label CTRL indicates the VSYNC, HSYNC and FIELD pins.
