Re: adv7604 custom res 1280 x 960

Hi,

Based on the timing provided, enter the following to the appropriate registers in the ADV7604 as outlined in the hardware manual.

Pixel clock = 105.948 MHz if VFreq = 60 Hz. If Vfreq 59.2 Hz, pixel clock = 104.53536 MHz

END_HS        =      114

SAV               =      418

EAV               =      1702

START_VS   =      1

END_VS       =      4

START_VBI  =      981

END_VBI      =        21

PLL DIV RATIO = 1800 = Htotal

LCOUNT MAX = 981 = Vtotal

Since the input is progressive, there is no need to program the VBI_EVEN registers. I hope the values given here helps.

Regards,

Edwin
