Note #1: With an effective loop capacitance of 4.0pF, the oscillator circuit will be within set-tolerance specification; less any frequency shift due to the
reflow process.
Note #2: The oscillator loop needs to present an effective loop capacitance of 4.0 pF to track the stand-alone crystal frequency. This
loop capacitance is
essential to ensure highest possible Closed-Loop Safety Factor for the entire population of crystals.
