This loop capacitance is required to ensure Safety Factor of > 5.0 for the entire population of crystals. Note #2: With an effective loop capacitance of 4.0 pF, the oscillator circuit will be with-in (32.768 kHz) ±20 ppm. Depending on production equipment capability, these parts might be tested at a different load, with guaranteed projected performance at 4.0 pF. ## — **FREQUENCY VS.
