MEMS oscillator at 27 MHz — what it replaces
The 2.25V to 3.6V supply range means it runs from a 2.5V or 3.3V rail without an LDO — the 35 mA max supply current is the load to budget in the power tree.
Standby power-down and frequency accuracy
The ±25 ppm absolute pull range (APR) sets the frequency accuracy over voltage, temperature, and aging — at 27 MHz that is ±675 Hz, tight enough for MCU clocking and USB full-speed.
