eQEP's maximum pulse frequency

Hello,

I recently find about about eQEP, and I was curious to know its maximum input frquency for pulses.

I have Pololu’s 50:1 Geared Motor with Encoder (64 CPR)

On one revolution of the geared shaft, it will give 64x50 = 3200 ticks.
At 200 RPM, it will give 3200x200 = 640k ticks per minute, that makes 10.6k ticks per second.

Will the Beaglebone’s eQEP support this much speed?

Yes, assuming your cabling is good enough, they are supposed to support up to a 4 MHz signal per pin.
