Signal value would be changing every 5ns. Would I be able to sample this signal and store it in memory?</P> Wed, 28 Jul 2021 10:45:40 GMT ankurkumar 2021-07-28T10:45:40Z https://community.nxp.com/t5/PowerQUICC-Processors/T1022-GPIO-sampling-rate/m-p/1314487#M3792 <P>Hello,</P><P>&nbsp;</P><P>&nbsp;I have been using T1022 in one of our design and running it with 100MHz system reference clock frequency.&nbsp;</P><P>Now I plan to supply a signal to its GPIO.
