logic analyzer circuit
I was planning a PC based logic analyzer. The idea is using a cache like sram (like 7cy199 or similar) and storing in it digital samples at high speed (40MHz) for later download to PC via PC port. First experiments demostrate concept is ok, but over 5MHz, strange digital noise appears.
Some circuit or trick?
Thanks on advance.
