Frequency Counter Chip

This might help:

Hmm...this might be a better idea. I want a wider frequency range than the PIC can handle though. Know of any good prescalers out there?

How high do you want? What kind of count range? Would a PLD clocked at

50MHz be fast enough? 64 cell Xilinx Coolrunner is about £2.50 in small quantities. (That's a guess on the speed by the way, it can be clocked much faster but the counter internals will limit the actual speed attainable.)
