MEMS timing with CMOS output and wide supply range
The MEMS resonator eliminates quartz crystal aging and vibration sensitivity, making it a drop-in solid-state replacement for crystal oscillators in industrial and automotive timing chains. Supply voltage spans 1.8V to 3.3V, so the same part can serve 1.8V, 2.5V, or 3.3V logic domains without a separate regulator or voltage divider on the oscillator supply pin.

Compact 4-SMD footprint and rework considerations
Housed in a 2.50mm x 2.00mm 4-SMD no-lead package with a seated height of 0.90mm max. The small land pattern fits tight PCB real estate but demands careful stencil aperture design to avoid solder bridging across the four pads. The no-lead package has no exposed side terminations — pad layout must match the recommended footprint in the datasheet. Pin 1 orientation is marked by a chamfered corner; verify polarity before reflow to avoid a 90° rotation that shorts the output to ground.
