9.7.3. Calibration Uncertainties

Calibration results may change or reduce due to one or more of the following uncertainties:
  • Jitter and duty cycle distortion (DCD) effects
  • Voltage and temperature variations
  • Board trace delays changing due to noise on terminated supply voltages

These calibration uncertainties are accounted for in the timing analysis.
