Hi

<3 Happy New Year 2013 <3

I want to implement PLL (Phase-locked loop) in STM32F4 Descovery Card
The Goal is to control output system frequency to be equal to the input frequency., to eliminate the noise effect

This is the diagram of PLL

I want to know have i to program any block only (PFD, LOOP FILTER) ?
Or are there any program implemented in STMEZF4 witch can be used directly ?

Thank You !
