    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://electronics-diy.com/schematics/BH1417_fm_transmitter.php

    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..

    You certainly mean MB instead of MD. http://radiomods.free.fr/doc/pll/mb1501.pdf

    I don't think to build any RF circuit it's sufficient to have a look at ONE website that describes a DIY RF transmitter project.

    1. What exactly do you want to do?
    2. What's your experience with RF circuits?
    3. Do you really need to BUILD a RF transmitter or can you buy on off the shelf?

    If you really want to learn about all types of PLLs and how they work I recommend reading the attached ebook.

    Thanks for yor reply.

    Actually, I will not make the FM transmitter, I just need to control the PLL systm with a microcontroller PIC.

    Thanks, I did the mistake, it is with "B", MB...

    I will read the pdf that you sent.

    Tnaks again...

    bye

    If I put MB1501 on google, this PDF file is the first one.

    It is free, right?

    Thanks by the way.
