    I'm doing my UG project using a 8051 microcontroller and I'm new to circuit designing.

    Clock freq to 8051 is 11.0592Mh. Then ADE7763 has 3.58Mh. how to interface them when having different frequency ?
    Thanks in Advance

    The 8051 and ADE7763 do not have to be clocked at the same frequency.
    The ADE7763 uses a standard color burst crystal at 3.579545MHz.

    You can clock the 8051 at any frequency, even at 3.579545MHz if you wish.
    The one constraint is if you require standard RS-232 communications.
