MEMS oscillator at 125 MHz with standby control
The supply range spans 2.25V to 3.6V, so it can run from a 2.5V or 3.3V rail without an extra regulator.
Microchip lists the DSC1101AI3-125.0000 as Active.

Microchip lists the DSC1101AI3-125.0000 as Active.
Yes — the part includes a Standby (Power Down) function. When disabled, the supply current drops to 95 µA max, compared to 35 mA max during active operation. This is a genuine power-saving feature, not just an output enable.
