[1]. No board level underfill. Measured as peak-to-peak/2. Inclusive of 3x-reflow and ±20% load variation. Tested with Keysight 53132A frequency counter.
Due to the low operating frequency, the gate time must be ≥100 ms to ensure an accurate frequency measurement.
[2]. Initial offset is defined as the frequency deviation from the ideal 32.768 kHz at room temperature, post reflow.
[3]. Core operating current does not include output driver operating current or load current.To derive total operating current (no load), add core operating current +output driver operating current, which is a function of the output voltage swing. See the description titled, Calculating Load Current.
