Its 2.25V to 3.6V supply range lets it run directly off a 2.5V or 3.3V rail without an extra LDO, simplifying the power tree.
Standby function for battery-conscious designs
When enabled, the 35 mA max active current is typical for a 25 MHz CMOS oscillator; the wide supply range means the current draw stays consistent whether the rail is 2.5V or 3.6V.
