ADG1414: Influence of clock signal at Pin 1 to 8 switches at other Pins S and D

ADG1414*  Why the clock signal connected to Pin 1 can be observed at other Pins S and D, the observed amplitude is about 50 mV at each switch (Pins S and D). How to solve the problem? Thank you!

    Hi Jufang,

    When designing your PCB board you should try and avoid running the Clock lines near the switch inputs/outputs. This will avoid any cross coupling. If possible you could also use different layers for the signals. You could also put a grounded shield between the traces if they have to run along side each other.

     

    for more tips you could also have a look at the following article:

    Regards,

    David
