No, the UDB can also be clocked with the maximum bus clock. But depending on how you configure it, the maximum frequency can be slower (e.g. for the counters it depends on the bit depth).

Max bus frequency is same like arm core frequency 67 MHz ?

   

 

   

My idea is very simple verilog VGA controller.

I raise to 80.02 MHz 🙂 (probably needs hydrogen cooling)

 Thanks help all

   

 

   

My VGA project working fine - 50MHz PLL and about 20% UDB resorces 🙂
