    Thread Summary
    
                The user asked if the ADV7524A can support 1440p (2560 x 1440) @25/30Hz. The final answer confirms that it can, as the pixel clock (122 MHz) for this resolution and frame rate is within the device's maximum clock limit of 150 MHz.

    Can the ADV7524A support 1440p (UHD, 2560 x 1440) @25/30Hz?
    

    We currently supply a 1080p60 video using a 148.5MHz digital input.
    

    By sending more data at the same rate, we could in theory send a 1440p (2560 x 1440) @25/30Hz video.
    

    But would the device be able to output this format?

      Hi,
      

        Yes, It can support '2560 x 1440@25/30p' resolution as long as it doesn't exceed the ADV7524A maximum clock (150 Mhz) .
      

      Generally, pixel clock is calculated as : 
      

         Pixel clock = Horizontal total pixels * Vertical total pixels * Vertical Frequency.
      

                           = 2720 x 1500 x 30
      

                           = 122 Mhz
      

      So ADV7524A can support 2560x1440@30Hz UHD Since its pixel clock is under 150 Mhz.
      

      

      Thanks,
      

      Poornima
