I currently have the following scenario:
A signal spike that has a rise and fall within 2-5 ns. This spike happens at a frequency between 30-50Hz.
After detecting the spike, I’d like to latch the output on high for about 2.5us or longer (for microcontroller input).
We’re looking into evaluation boards using high speed comparators in the picosecond range. Can you recommend any available evaluation boards that would meet these requirements?
