My application involves driving a digital-output (PDM) MEMS microphone at 1 -- 3.25 MHz with a clock generated on a GPIO.
The output of the microphone is a digital signal with data at the rate of the supplied clock. I'd like to sample this I/O at the highest rate possible; is this a scenario I can achieve with the nRF51822? (Assume a 16 MHz input clock to the nRF51822.)
