It draws 6.3 mA max from a 1.8V to 3.3V supply, and the standby (power-down) function drops consumption to 15 µA max when the clock is gated.
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm x 0.90 mm — the exposed paddle on the bottom requires a thermal via pattern under the part to pull heat into the ground plane.
That covers under-hood and cabin domains where a standard commercial oscillator would drift out of spec.
