LVDS cycloneII to 10 bit counter

In cycloneII manual i read the max freq input LVDS pin is >800MHz. IF i have a 750 MHZ signal as input, and i send it to LVDS input (cycloneII), can i divide this freq with a 10-bits counter? ...

tnx to all.

i Need to measure microwave frequency of a pulsed signal.

The freq range is 5.4GHz-5.9Ghz, and the width pulse is 0.5uSEC(min).

I have got an external prescaler divider (div8).

example for f=5.6GHz: width=0.5uSEC

5.6Ghz/8= 700MHz

in a time of 0.5uSEC i have 350 pulses.

if i measure with a counter (9 bit counter in this case) these pulses number, i can measure the frequency.
