Hi Pros,
I need to count a TTL level high speed pulse train, rise time 1ns, fall time 1ns, pulse width 10ns, period 20ns.
I see that a lot of MCU input are not fast enough to capture such a high speed pulse, even some 24bit asynchronous counter, the parallel output is only the last 8bit, means the lower 16 bit information is missing.
I wonder, normally how this high speed pulse train is counted with high resolution(at least 18 bit resolution).
I heard FPGA is a possible option, can somebody advise why FPGA is an option?
