Product details

Supply voltage range and output compatibility

The oscillator accepts a 2.25V to 3.6V supply, covering both 2.5V and 3.3V logic rails without an external LDO. This simplifies the power tree on mixed-voltage boards — the same part can serve a 3.3V MCU or a 2.5V FPGA bank. CMOS output drives standard digital loads directly; the 25 MHz frequency with ±50 ppm stability keeps clock jitter within the tolerance of most MCU PLLs and USB controllers.

Package, footprint, and sourcing posture

Housed in a 6-SMD, No Lead package measuring 7.00 mm × 5.00 mm × 0.90 mm, this is a standard MEMS oscillator footprint — it drops onto the same land pattern as many quartz XO alternatives.
