Hi team

can 947 pattern support this resolution 2396*1094*60fps with internal clock? the PCK is about 160MHz.

Check document of 947, it support 800MHz OSC, how to select M/N to generate this resolution?

customer try to use M=2 N=10, it can't work. 

in additional, use ALP tool, can't select M/N and the max PCLK is 100MHz. we did not connect the 947, does it needed for M/N adjust?

thank you

    Hello Betty,

    Yes, 947 should be able to support this resolution with internal clock although the frequency is not expected to be well controlled when using the internal oscillator. M = 2, N = 10 should also work but you may need to force dual link mode in the 947 for this to work. 

    The ALP GUI you are showing looks outdated which is why you are not seeing the M/N values. Please download and install the latest profile updater tool from the ALP product page to get the latest version. 

    Best Regards,

    Casey
