Hi
I need an analog video Mux (Quad 2:1 ) and one 2:1 for anaog video multiplexing. Is PI5V330 and LMH6570 are suitable for my application ?
any other suggestion ?
or LMH6572 and LMH6570 are suitable ?

Hi Neelam,
TI does not have a high speed analog quad 2:1 MUX. Here is the parametric table of MUX's:
The LMH6572 is a triple 2:1 MUX, but that is one short of what you need. It would work well with a CVBS signal provided you ensure that you comply with the device input voltage range (CMIR of +/-2.5V typical with +/-5V supplies). AC coupling is a good choice here, if your application allows it.
To get 4 channels, the alternative is to go with four LMH6570's (single 2:1). Or, one LMH6572 (for 3 channels) + one LMH6570 for four total channels.
