I'm trying to build a circuit that gives the user the option of using the functions of a particular IC or not. In this case, the LM1881N which is a sync stripper. It is fed a componentcomposite video signal, removes the video information and outputs a composite sync signal (csync) which will then go to a monitor. I want to have the option of switching between composite video and csync but I'm unsure of the simplest method of switching. I've considered a DPDT switch that will bypass the IC and send the composite video signal directly to the monitor but I'm not certain if this will work or what possible ramifications this option may have.
