The MEMS base resonator inherently withstands higher mechanical stress than a quartz blank, so the part holds frequency during board flex or high-vibration environments like engine bays or industrial pumps.
Operating from 1.8V to 3.3V, the oscillator can be powered directly from a 1.8V core rail or a 3.3V I/O rail without an intermediate regulator—simplifies the power tree in mixed-voltage designs. Maximum supply current is 8.7 mA at 125 MHz, which is lower than a typical quartz oscillator at this frequency.
