Note #2: The oscillator loop needs to present an effective loop capacitance of 3.0 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. Note #3: Ts = - (C1) / [ 2*(C0 + CL)[2] ] ……….
