Dear Experts,

     my customer is using the ADV7441A and AD9388 for the VGA+HDMI input, now they want to cehck whether the parts can support the WUXGA 1920x1200 60Hz resolution;

    As the ADV7441A/AD9388A ADC sampling rates up to 170 MHz, the whole WUXGA 1920x1200 60Hz resolution timing exceeds the limit, so i think it can not support this, but for the WUXGA 1920x1200 Reduced Blanking  60hz @154MHz pixel clock, we find the reference setting on our script file, it should be supported,  so it is clear on Analog RGB input;

   but for the HDMI input, it support 225 MHz HDMI receiver, i know it mainly for the 1080P/UXGA 12bit deep color support; can it support the whole WUXGA 1920x1200 60Hz resolution as the pixel clock < 225Mhz?  as myknoledge, it should not support as the CP block clock limite is also < 170Mhz;  and how about the WUXGA 1920x1200 Reduced Blanking  60hz @154MHz HDMI input??

   need your help to confirm it! Thanks

 

Regards

Joseph
