    Hi,
    I'm doing a project in clockless uart..as u know that the primary
    function of uart is parallel to serial conversion while transmitting
    and serial to paralel conversion while receiving..I was wondering if
    someone could tell me as how can i do a parallel to serial conversion
    and vice versa without using a clock.

    Note: This is a circuit whoch doesnt use a clock at all/ Asynchronous
    Circuit/Clockless Circuit.

    Thank You

  2. Guess your mixing up asynchronous logic and asynchronous transmission. The
    first is event driven without using a clock, the latter is sending data at
    unpredictable times but uses a clock that has to be synchronised the
    receiver side at the beginning of every data word.
