No board level underfill. Measured as peak-to-peak/2. Inclusive of 3x-reflow and ±20% load variation. Tested with Agilent
53132A frequency counter. Due to the low operating frequency, the gate time must be ≥100ms to ensure an accurate
frequency measurement.
Initial offset is defined as the frequency deviation from the ideal 32.768kHz at room temperature, past reflow.
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, where output driver operating current = Cdriver*Vout*Fout.

Functionality
Connect to ground. All GND pins must be connected
to power supply ground. The GND pins can be
connected together, as long as both GND pins are
connected to ground.
Oscillator clock output.
Connect to power supply 1.5V≤Vdd≤3.63V. Under
normal operating conditions, Vdd doesn’t require
external bypass/decoupling capacitor(s). Internal
power supply filtering will reject more than
±150mVpp with frequency components through
10MHz.
