Supply voltage spans 2.25V to 3.63V, covering 2.5V and 3.3V rails without a separate regulator — the oscillator draws 32 mA max from the rail. ## Temperature grade and deployment fit ## Package and board layout note Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the small footprint leaves room for the differential pair routing and the decoupling cap right at the supply pin.
