In my application(i.MX8M Nano Dual) i do not need any of the CLKINx and CLKOUTx functionality.

can i leave these pins(H26/H27/J26/J27) unconnected or should i pull them to a certain voltage level.

thanks in advance,

Hello Arne Maathuis,

CLKINx pins can be used to drive some of the internal PLL instead of the SYS_XTAL. If you won’t be using these pins these can be left floating.

I hope this helps!
