Any help with a PLL theory to FM transmitter?
« on: July 27, 2011, 02:17:10 AM »
So people, I searching for some data that explain how a PLL system works on a FM transmitter...

I found one website that do it: http://hem.passagen.se/communication/fm_pll_vco.html

IF I a understood correct, I need to apply a ref frequency on the PPL and it will do the rest. Hun?

My project needs to have a PLL MD1501. But i did not find anything about this CI (MD1501).

Anyone may help me please?

Thanks..
