Jayee165:
What is the best product to use if I am trying to obtain 36mhz?
I presume you mean 36 MHz? Not 36 milliHerz?
You won't get that out of an Arduino, whose clock is only 16 MHz (20 MHz tops with a different crystal).
Perhaps it's time to explain your project. Why do you need 36 MHz? Are you making a radio station?
