Nothing in particular, but it's just that a computer is not the right
tool to generate a stable high frequency signal.

What is wrong with using a PC ?
Use all 8 bits of the parallel port in DMA mode.
The make an external circuit which will buffer and then serial clock the 8
bits out.
If this is not quick enough, use more parallel ports.
It is probably a good idea to use a real time OS, and not linux.
Linux current
