It operates from a wide supply voltage range of 2.25V to 3.6V, making it compatible with 2.5V and 3.3V logic rails without an external regulator.
Housed in a 6-SMD, no-lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard footprint for high-frequency oscillators.
Yes, the base resonator is MEMS, which provides better shock and vibration immunity compared to quartz crystal oscillators.
