How to use this tool

Enter the labeled inputs in the indicated units.
Calculate and compare every output against the stated model assumptions.

Try this example

{
  "f": 10000000,
  "clock": 3e-12,
  "aperture": 4e-12
}

Accuracy and scope

Independent RMS jitter; sine input and small timing error approximation. Simplified analytical model; not a design recommendation or safety certification.
