I am trying to implement a classic PLL actually; I've just never done it in software before. What I basically need to do is lock onto an incoming 31.250KHz Signal with the PLL. The outputs should be 2 frequncies, one at 5MHz (incoming times 160) and the other should be 20MHz. Whats the simplest way to achieve this? (this is my challenge in a nutshell)
