Hi.
some video buffer splitter chips.
Analog devices sells something that can do that for $2:

Hi All,
I have 1 composite video source and I would like to split in to 2 inputs
Can you recommend some video splitter ccts like emitter followers (buffers) or some video buffer splitter chips.
Regards Joseph
Use courier or other constant-width font for this ASCII-art schematic:
|\ | \ 75 in-------+--------+---|+ \_________/\/\/\----out1 | | |- / | | | | / | | | |/ | | | | | +--+/\/\/\---+ | | R | \ | / | \ R | / | | | GND | | |\ | | \ 75 +--------+---|+ \_________/\/\/\----out2 | | |- / | \ | | / | / 75 | |/ | \ | | / +--+/\/\/\---+ | | R GND \ / \ R / | GND
The op-amp could be, for example, the LT1364CN8, which is in-stock at digikey. Numerous details are not shown. You will need to have bypass capacitors, and a +/-5 V power supply. I don't know that this is the best or cheapest way to do this. This op-amp is just the first one I found at digikey that looked like it would do the job.
Read the datasheet for the full details.
Or just go to
Have fun.

I read in sci.electronics.design that Mac wrote (in ) about 'video splitter', on Mon, 2 May 2005:
.... which is seriously in error. The feedback is positive and the inverting input of each op-amp is not connected to anything.

Which, as John Woodgate pointed out elsewhere, is seriously in error. I've fixed the one below.
|\\ | \\ 75 in-------+------------|+ \\_________/\\/\\/\\----out1 | +---|- / | | | | / | | | |/ | | | | | +--+/\\/\\/\\---+ | | R | \\ | / | \\ R | / | | | GND | | |\\ | | \\ 75 +------------|+ \\_________/\\/\\/\\----out2 | +---|- / | \\ | | / | / 75 | |/ | \\ | | / +--+/\\/\\/\\---+ | | R GND \\ / \\ R / | GND
My apologies (especially to the OP) for posting such a fundamentally flawed schematic.

Thanks. I fixed it (I hope!) elsewhere in the thread.
