Part Number: LMX2615-SP

Tool/software:

Is there an input capacitance (Ci) and dynamic capacitance (Cpd) available for the part LMX2615-SP?

Thank you

Hi There,

I assume you are talking about the OSCin input.

I don't aware we have dynamic capacitance. Input capacitance, if I remember right, it is just a few pF.

Hi Noel,

Apologies for the delay. We are actually looking for the total internal parasitic capacitance of the device itself. Just to confirm, you don't have the total dynamic capacitance for the device LMX2615-SP?

Additionally, do you know if there is an input capacitance (Ci) value for the digital inputs?

Thank you

Hi There,

Pin capacitance should be included in the IBIS model.

Other than this, I don't have any other data.
