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
SHASHI

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.
