1.2 GUI Controller Programmability and
Frequency Requirement
Programmability and frequency requirements for the Graphics Controller/Data
Master device are defined in
8 percent to 32 percent horizontal and vertical overscan compensation. For larger
overscan compensation percentages, the values would be larger. The maximum
pixel frequency supported is 53.333 MHz for standard clocking mode and 80.000
MHz for 3:2 clocking mode.
