Supply voltage spans 2.25V to 3.6V, so it runs directly from 2.5V, 3.0V, or 3.3V rails without an extra LDO.
Housed in a 6-VDFN package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — a compact footprint that matches standard 3.2 x 2.5 mm oscillator pads.
Yes — it is a MEMS-based XO with CMOS output and the same 3.2 x 2.5 mm footprint as many quartz oscillators. The Enable/Disable function adds control not always available on quartz parts.
The output is CMOS, which interfaces directly with most digital logic families without level translation.
