Does anyone have, or know where I can find some information on an Analog Demultiplexer that can generate the clock from the incoming data, seperate the data and detect the null string.
It sounds like you are looking for some type of serial reciever. If you know the protocol, I could probably help.
If you are not talking about a serial device you could probably write something that can do what you are describing but its feasability is dependent on how fast the data is transmitted. Reply with more details if I have come close with any of my guesses.
