66AK2G12: Input capacitance ?

Part Number: 66AK2G12

Hi,

My customer wants to know Input capacitance information for 66AK2G12 pins. I checked the datasheet, but i could not find the spec. Do you have any suggestions ?

Best Regards,
NK

  • Hi NK,

    I'm not sure what you are asking for.  Are you trying to define the bypass capacitance needed for the power delivery network?

    Hi, Bill

    Thanks for your reply. My customer is considering to use a buffer to distribute clocks to K2G and other system parts. In the perspective of fanout, it seems like they would like to know the input capacitance for IO pins of K2G. Does it answer to your question ?

    Hi NK,

    Based on your question it sounds like you are planning on driving multiple clock inputs with a single buffer. I would recommend you avoid this. Reflections on clock signals can cause noise on the clock input to the device creating false edges and, possibly, false clock inputs into your part. I strongly suggest you drive each clock with it's own buffer. Clock distribution parts are available that will keep these clock edges close.
