Hi,
You may say "not correct"...
but I did just a general calculation of the required minimum input frequency .. (for any digital PWM generation, not only MAX9685)
and if the minimum required frequency is 200MHz then I saw no need to do further calculations.
For sure I can do: 200MHz x 4 (min prescaler) = 800MHz.
Still above 50MHz, still not possible.

Hi,
What PWM resolution do you need?
Whay exactly 50kHz? What tolerance / range do you allow?
PCA9955 operates with 31.25kHz... this is the closest on a quick view.
But any small FPGA will do. What quantity? Maybe you find someone coding and programming it for you.
