Question

Hi all,

My group and I are brand new to FPGAs, none of us have any expertise whatsoever.  As such, we have a few questions about the capabilities of the PYNQ-Z1 board that some of you seasoned experts can help us out with.

First: we will have a TTL (3.3 V) pulse sent to the board which is about ~10 ns long.  Can the board detect such a pulse from something like a rising or falling edge?  We hope to send this pulse via BNC connection - where could we input this on the board?

Second: We also need to output a pulse via BNC connection.  Where would this pulse be outputted from?

Third: Given the first two questions, should we invest in the following two items?

i. https://store.digilentinc.com/pmod-cable-kit-6-pin/  ii. https://store.digilentinc.com/bnc-adapter-for-analog-discovery/

Sorry if these questions seem hopelessly basic.  We are new to this type of hardware and would greatly appreciate any help you all could send our way.

Hi @cole12345,

The BNC Adapter should work just fine since it is just a pass through. We can not guarantee that you will be able to get 100 MHz from the pmod ports.   Here is a forum thread the discusses using the Pmod Ports with higher frequencies on a different development board.

thank you,

Jon
