i have a digital 8 bit output sampling video at 5 MHz but i need to multiplex the 8 bit digital output to send the data down a single wire. i may have to use a UART but i am not sure if i can get away with just a multiplexer and demultiplexer. has anyone any experience in this sort of data transfer? any tips welcome.

Have I understood you correctly - are you digitising analog video into 8-bit samples at a 5MHz sampling rate? If so, then to send this down a single wire requires a data rate of 40Mb/sec (8 x 5MHz) and if you want to use a typical UART this requires a x16 clock (640MHz !!!). I don't know of any UART devices that run at even a fraction of that speed.

Hi, it would be alot easier to send it down the wire as analouge video.
If you're game, AMD and Cypress have a chipset for HotLink, which is a serial bus similar to Firewire. The chipset comes with serializer/deserializer and drivers for the cable.
We've used it for our video transmission system running around 250 Mb/s.
