Operating from 2.25V to 3.6V, the oscillator accepts both 2.5V and 3.3V rails without an external regulator — a single BOM line covers mixed-voltage designs. The Enable/Disable function (pin 1 on the 6-SMD package) pulls the output to high-impedance when driven low, reducing supply current from 35mA max to 22mA max — useful for power gating in battery-backed or sleep-mode systems.
