    What is the best way to learn about PLL and DLL and their differences?

    I wan to become intimate with the PLLs and DLLs. I think the best way is to design and operate them in simulation and on bench. However, I am not sure where to start. It is possible to create them in MATLAB Simunlink (maybe) to learn about how the mechanism works. But I don't know if they can be constructed using different components on bench or can only work in an integrated circuit.

    Please advise.

    Sure, if you know how to build the PLL functions (vco, phase respectively phase/frequency detector and loop filter) from discrete components.

    Hi,

    There are a lot of informations, documents, tutorials, videos about DLL and PLL in the internet.

    I assume you already worked through some of them.

    I think it's a good idea to tell us which ones you used ... then you can tell us what you understand so far and what is unclear.

    PLL Tutorial

    http://www.delroy.com/PLL_dir/tutori...ial_slides.pdf

    From TI:

    PLL Handbook

    http://www.ti.com/tool/PLL_BOOK

    PLL Simulation

    http://www.ti.com/tool/PLLATINUMSIM-SW

    Analog Devices PLL Simulation

    https://form.analog.com/form_pages/r...adisimpll.aspx

    Phase-Lock Basics, 2nd Edition
    William F. Egan

    Has MATLAB Code available for download to learn PLL

    Free Software is here:

    ftp://ftp.wiley.com/public/sci_tech_med/phase_lock

    DLL

    Must read research and papers, not really any book on it specifically.

    For example try: https://www.ece.ucsb.edu/~long/ece594a/DLL.pdf

    I would like to know if there are any books that explain the design and working principles of DLL.

    Re: What is the best way to learn about PLL and DLL and their differences?

    Hello,

    DLL is mostly covered in books and book chapters along with PLL.

    Razavi has a good reference paper and tutorial on DLL in his book:

    Phase-Locking in High-Performance Systems: From Devices to Architectures Paperback
    by Behzad Razavi

    This paper I linked in previous message is the best tutorial on the subject:
    https://www.ece.ucsb.edu/~long/ece594a/DLL.pdf

    Other than that it is course notes from universities and patents and papers that help you to do DLL.

    To my knowledge there hasnt been a book dedicated to DLL released. I could be wrong.
