The MEMS base resonator means no quartz crystal aging or startup reliability concerns; the oscillator starts up in under 5 ms typical and holds frequency across the supply range of 2.25 V to 3.6 V without external load capacitors.
Yes, if the board is designed for a 7.00 mm x 5.00 mm 6-VDFN footprint with CMOS input. The MEMS oscillator eliminates the need for external load capacitors and provides faster startup than a quartz oscillator. The ±25 ppm APR covers most Ethernet, PCIe, and processor reference clock requirements.
