The primary output is 25 MHz; the second output is 24.99875 MHz (part of a family including 24.998125 MHz, 24.999375 MHz, 25.000625 MHz, and 25.0025 MHz variants). Supply voltage spans 2.25V to 3.6V, making it compatible with 2.5V and 3.3V logic rails without an external regulator.
Housed in a 14-VFQFN exposed pad package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm.
The oscillator provides two CMOS outputs: one at 25 MHz and one at 24.99875 MHz. The second output is one of seven possible frequencies in the F0042 variant set, which also includes 24.998125 MHz, 24.999375 MHz, 25.000625 MHz, and 25.0025 MHz.
Yes, it is a drop-in functional replacement for a standard quartz XO in the same package and pinout. The MEMS resonator offers better shock and vibration tolerance compared to quartz, and the ±25 ppm stability meets the same timing budget as many quartz oscillators. Confirm the specific output frequency pair matches your BOM requirement.
The part is listed as RoHS compliant by Microchip. The 14-VFQFN package is lead-free and compatible with lead-free reflow profiles.
