If I understand the hostmot2 documentation, the 100MHz PWM clock is standard on 5i20, and allows pwm frequencies up to 193kHz.
Here's what it actually says: (u32 rw) pwm_frequency: This specifies the PWM frequency, in Hz, of all the pwmgen instances running in the PWM modes (modes 1 and 2). This is the frequency of the variable-duty-cycle wave. Its effective range is from 1 Hz up to 193 KHz. Note that the max frequency is determined by the ClockHigh frequency of the Anything IO board; the 5i20 and 7i43 both have a 100 MHz clock, resulting in a 193 KHz max PWM frequency. Other boards may have different clocks, resulting in different max PWM frequencies. If the user attempts to set the frequency too high, it will be clipped to the max supported frequency of the board. Frequen‐ cies below about 5 Hz are not terribly accurate, but above 5 Hz they’re pretty close.
