Mode Descriptions
4:4:4—All channels come out with their 8 data bits at the
same time. Data is aligned to the negative edge of the clock
for easy capture. This is the normal 24-bit output mode for
RGB or 4:4:4 YCbCr.
4:2:2—Red and green channels contain 4:2:2 formatted
data (16 pins) with Y data on the green channel and Cb, Cr
data on the red channel. Data is aligned to the negative
edge of the clock. The blue channel contains the secondary
channel with Cb, Y, Cr, Y formatted DDR 4:2:2 data. The
data edges are aligned to both edges of the pixel clock, so
use of the 90° clock may be necessary to capture the
DDR data.
4:4:4 DDR—This mode puts out full 4:4:4 data on 12 bits of
the red and green channels thus saving 12 pins. The first
half (RGB [11:0]) of the 24-bit data is sent on the rising
edge and the second half (RGB [23:12]) is sent on the
falling edge. The 4:2:2 DDR data is sent on the blue
channel, as in 4:2:2 mode.
RGB [23:0] = R [7:0] + G [7:0] + B [7:0], so RGB [23:12] =
R [7:0] + G [7:4] and RGB [11:0] = G [3:0] + B [7:0]
