DRA71: HDMI module in Dra71x

Part Number: DRA71

Hi.

     Now we want to use the HDMI in dra718.

    We need to output the video throuigh the HDMI interface, but we not sure wether the module support non-standard resolution ,such as 1280*276.

    Please help confirm wether the HDMI module can support non-standard resolution such as 1280*276.1280*300...and so on.

    Thanks.

  • Per the TRM, DRA71x supports P-CLK speeds up to 148.5 MHz. 

    Assuming standard blanking timing configuration, 1920x1080 resolution = 148.5MHz P-CLK.

    Again assuming standard blanking timing configuration, 1280x276 would require about a 23MHz P-CLK.

    Because of this, the DSS hardware can support the non-standard resolution that you inquire about. However our TI-supported Software drivers have not implemented these custom resolutions. If you would like to proceed with developing for a non-standard resolution, the Hardware can support the application but the Software would have to be developed and integrated entirely by the customer.
