Output is 10 MHz CMOS, ±10 ppm frequency stability, and 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.
Packaged in a 6-SMD, No Lead Exposed Pad footprint (7.00mm x 5.00mm, 0.90mm seated height) — the exposed pad requires a thermal via pattern under the package for proper heat transfer to the PCB ground plane.
Yes, it is a drop-in MEMS replacement for a 10 MHz quartz oscillator in a 7x5 mm SMD package. The MEMS base resonator eliminates quartz aging and offers better shock/vibration tolerance. The supply voltage range (2.25V to 3.6V) covers common 2.5V and 3.3V logic rails. Confirm the output type (CMOS) and enable/disable logic polarity match your existing circuit.
