I have an application where two CCD video cameras have to be genlocked.

There seem to be two routes available:
	1) for those cameras accepting a composite genlock signal, we
	   can use a distribution amplifier to split the video output
	   of one camera into two parts.  The first part is used as normal,
	   the second is used as the genlock input to the second camera.

Question: does anyone know of a (cheap) amplifier that would be appropriate?
	  Could we build our own with a suitable op amp (must run at 12V,
	  though)?

	2) for cameras expecting HD/VD, we need a sync generator.  The only
	   ones I have been able to find cost $3K - $4K, which exceeds our
	   budget enormously.  We do not need something that is broadcast
	   quality (it would be wasted on the equipment we have!).  I'm
	   amazed at the difficulty/cost we have faced.  After all, every
	   cheapo video camera and graphics board has a sync generator built
	   in.

Question: do cheap video sync generators exist?  Can we build one ourselves?

Thanks.
