I need to put some digital iinfo, from a fast uart, possibly,maybe
biohase mark, into a few lines of video blanking, on a standard 75R
coax. 2 or 3 bytes per line will be ok
I was thinking of just using a simple PNP current source, from a
5Vish rail, fed from a micro, 8051 or similar.
I'll have an Elantec sync stripper doing a lot of the hard work/
timing, somewhere in the system.
Any gotchas on feeding a coax this way?
