The supply voltage spans 2.25V to 3.6V, so it can run from a 2.5V or 3.3V rail without an external LDO, simplifying the power tree.
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — a standard footprint that matches many quartz oscillator pads.
Yes — it carries AEC-Q100 qualification, which covers the reliability and temperature requirements for automotive electronics, including engine bay and cabin modules.
The output is CMOS, which is the standard single-ended logic level for most digital clock inputs.
