The MEMS resonator is sealed in the package, so it handles vibration and shock better than a quartz can in an automotive or industrial environment.
Supply voltage spans 2.25V to 3.6V, which covers 2.5V and 3.3V logic rails without an external regulator.
CMOS output — it drives standard digital logic inputs directly without external termination or level translation.
Yes, if the original was a 25 MHz CMOS-output oscillator in a 7.0 x 5.0 mm 6-pin SMD package with a 2.25V–3.6V supply. The MEMS-based part is a drop-in replacement, no board changes needed.
MEMS oscillators use a silicon micro-electromechanical resonator instead of a quartz crystal. They are more resistant to vibration and shock, have shorter startup times, and typically offer tighter frequency stability over temperature without the need for external load capacitors.
When the enable pin is pulled low, the output is tri-stated (high-impedance) and the core current drops to a maximum of 22 mA — useful for power gating the clock in sleep modes.
