PLL Loop filter Analysis Method with oscilloscope

Hi everybody,

In the embedded world, there are two domains: the digital and the analog world. Analog domain with oscillators and PLLs are blocks providing clock sources for the other one domain.
In the embedded application, usually the user does not know to evaluate the correct working of the PLL according to the used PLL Loop Filter.
Here is a small technical paper which gives you guidelines to achieve measurements and eliminate (or not) PLL issue.
This paper note can be used for all AT91 which embeds PLL clock generator.

Hope this helps.

Hi,

Just click on the attach by using the right button and select 'Copy the target under...', do not try to open the attach directly via the forum by a left click.
I have just try it and it works fine.

It would be nice to see this document, because I have also a problem and the PLL could be the reason for that. Thanks!
