The oscillator operates from a 2.25V to 3.6V supply rail, covering common 2.5V and 3.3V logic domains without an external regulator.
Housed in a 6-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm. The no-lead construction keeps the footprint compact and the parasitic inductance low — the pad layout should follow the manufacturer's recommended land pattern for the 6-pin MEMS oscillator to avoid start-up issues.
Yes, it carries AEC-Q100 qualification, meaning it has passed automotive-grade reliability stress tests including temperature cycling, ESD immunity, and latch-up. This qualifies it for under-hood and cabin electronic modules where vibration and thermal cycling are present.
