HI guys this is one i have not tried as yet , and wonder if its at all possible

i have high speed differential optic TIA (600mhz) connected to a 2nd stage amp with high gain , with outputs that are also differential at 3.3v

the output gives 15ns - 100ns pulses , which i need to count / check further in the pic for pattern / timing

is there a way that i can interface directly to the PIC todo the pattern checking and counting on a 18f 64mhz device ?

if not any other interface suggestions such that the pic could do it


Cheers

sheldon
