Hi, I want to build a MCU-free frequency counter and I have found this circuit (attached). Several of these can be cascaded for measuring higher frequencies.
However it's max input frequency is something like 10MHz or so, at 12v.
I am looking for another variant that can do up to 30MHz.
Can you please suggest one?
