Internal Oscillator Frequencies for Intel MAX 10 Devices

Why don't you take the oscillator frequency as typical frequency value and try the control motor driver with that. I think that works. I use internal oscillator for a timer assume that the frequency is typical value and it works in my case.

I have controlled a simple BLDC motor using PWM and Hall sensors on a MAX10 with only the internal oscillator. We had 10 different cards and the frequency we measure on the Internal Oscillator differed from 78 to 83 MHz. It was pretty stable on each PCB though so we got it working but the speed of the PWM and all communication protocols we used was of course directly connected to the different speed of the system clock.

So yes you can do it. But depends on your requirements on the motor control.
