2.4.6. Carrier Based 24 bit Color Depth LVDS
For 24 bit color depths, four LVDS channels are used (24 data bits + 3
control bits + 1 unused bit = 28 bits, or 4 x 7) plus a clock pair. The LVDS
clock is transmitted on a separate LVDS pair. The LVDS clock period is 7
times longer than the pixel clock period. The LVDS clock edges are off from
the 7 bit frame boundaries by 2 pixel periods.
