Preliminary data sheet
Display Modes
4:2:2 CVBS or Y/C
PAL/NTSC/SECAM resolution 4:2:2
Example PAL:
864 pixel/line x 312.5 lines/field x 50Hz = 13.5MHz/Y samples
7.5 MHz/U samples 7.5 MHz/V samples
4:4:4 RGB or YUV
PAL/NTSC/SECAM resolution 4:4:4
Example PAL:
864 pixel/line x 312.5 lines/field x 50Hz = 13.5 MHz/
component
4:4:4 RGB or YUV
2FH
(double line frequency -> double refresh rate)
Example PAL:
864 pixel/line x 312.5 lines/field x 50Hz x2 = 27 MHz/
component
4:4:4 RGB or YUV
480P (PAL/NTSC resolution, progressive)
Example PAL:
864 pixel/line x 625 lines/field x 50Hz = 27 MHz/component
4:4:4 RGB or YUV
1920x1080@60I
Example:
·1920 active pixels per line (2200 total), 1080 active lines per
frame (1125 total), 30 frames (60 fields) per second
= 2200x 1125x 30 = 74.25 MHz
