4.4.3.1 High Definition 1080p Output Formats
ITU-R BT.1120 also includes progressive scan formats with 1080 active lines, with Y'C'_BC'_R
4:2:2 sampling at pixel rates of 74.25MHz or 74.25/1.001 MHz. The following diagrams
show horizontal and vertical timing for 1080-line progressive systems. The GV7704
provides a 10-bit multiplexed output interface, doubling the pixel clock output rate to
148.5MHz or 148.5/1.001 MHz.
