The 2.25V to 3.6V supply range lets it run directly from a 2.5V or 3.3V rail without an external LDO, simplifying the power tree in mixed-voltage designs.
Housed in a 6-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the footprint matches industry-standard 5.0 x 3.2 mm oscillator pads — no layout change needed if replacing a quartz oscillator in the same form factor.
Yes, it carries AEC-Q100 rating, qualifying it for automotive applications including under-hood and chassis domains.
Yes, the Enable/Disable function allows the output to be gated, reducing supply current from 35 mA to 22 mA when disabled.
