About the load capacitor of CDCLVC1106 (CDCLVC11xx)

Other Parts Discussed in Thread: CDCLVC1106

Are there some which were specified as the maximum of the load capacitance (C_load) of CDCLVC1106?

There is an example of 2pF×n in a data sheet.
Does it become a problem with a larger value?
It will be saved if there is especially the calculation method.

Thank you for your consideration.

    Larger output cap load could lead to increased dynamic power consumption, increased output rise/fall time, and possibly reduced output swing depending on the clock frequency due to output RC time constant.

    Please refer the power consideration section in the datasheet.  You may also use IBIS model to simulate the output transient response due to output cap load.
