Typical Frequency Tolerance Distribution (at 25ºC ± 3ºC):
ABS04W-32.768 kHz -
Note #1: With an eective loop capacitance of 4.0pF, the oscillator circuit will be within set-tolerance specication; less any frequency shift due to the
reow process.
Note #2: The oscillator loop needs to present an eective 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.
Note #3: Ts = - (C1) / [ 2*(C0 + CL)2] ………. Where CL = 4pF
