Description
Four kinds of analog video output supoorted: CVBS(composite)/S-video(Y/C),
YCbCr(comp onent), RGB(component) and YPbPr Progressive scan.
Mode 1: CVBS + S-video(Y/C)
Mode 2: CVBS+YCbCr
Mode 3: CVBS+RGB
Mode 4: YPbPr
This pin is:
In mode 1: (CVBS) analog composite signal output.
2: (Y) analog luminance signal output.
3: (G) analog Green signal output.
4: (Y) analog progressive luminance signal output.
This pin is:
In mode 1: (Y) analog luminance signal output,
2: (Cb) analog chrominance signal output.
3: (B) analog blue signal output.
4: (Pb) analog progressive chrominance signal output.
This pin is:
In mode 1: (C) analog chrominance signal output,
2: (Cr) analog chrominance signal output.
3: (R) analog red signal output.
4: (Pr) analog progressive chrominance signal output.
This pin is:
In mode 1: (CVBS) analog composite signal output.
2: (CVBS) analog composite signal output.
3: (CVBS) analog composite signal output.
4: (Y) analog progressive luminance signal output.
Full-scale adjust control pin. The full-scale current of DAC is controlled by
connecting a resister (R ) between this pin and A VSSref. The full-scale current I
