adv7513 SXGA @ 30Hz

Hello,

Currently, I'm transmitting an input video to the ADV7513 from an FPGA in SXGA resolution (1280x1024) @ 60 Hz using external syncs (Hsync,Vsync,DE) and it's working. I required to change the frame rate to 30Hz (Same pixel clock, different porches) but didn't understand the programming guide clearly. Which registers controls it? Does the ADV7513 supports SXGA @ 30Hz?

    Hi,

      Yes, ADV7513 can handle SXGA30.

      The following script would work for SXGA (1280x1024)

    :6-1e Port A, 720p,1080i Any Color Space In (YCrCb 444 24bit from ADV761x) Through HDMI Out 444 YCrCb VIC[4,5,19,20]:

    Please note that these scripts assume the ADV7513 is connected in a manner similar to the ADV7511 on the EVAL-ADV7611EBZ.

    Thanks,
