Can a 16MHz signal input to the gpio pin of nRF52832?

[chenlmm]

My system's data rate is 16MHz.it input to nRF52832 is parallel 8 bits. Is it possible? I want input the data to RAM by easyDMA,please to tell me how to do it ? thanks!

There seems to be no such "parallel 8-bit" port on nRF5x chips, not speaking about 16MHz clock input. I guess you need specific chip which will be able to handle this and transfer it to nRF52 over some serial interface (still it will be basically impossible to handle 16x8=128Mbps transfer, no interface can manage that and there is no space for storing MB of data so you will run out of space in few seconds of such transfer). nRF53840 with USB and QSPI might be better but still you cannot utilize this over radio so one would wonder why using nRF5x chips for such high throughput application...
