Supply tolerance and package footprint
Supply voltage range 2.25V to 3.63V covers both 2.5V and 3.3V rails without an external regulator — the oscillator starts and stays within spec across the full tolerance.

Frequently asked questions
Can the DSC1123AI2-148.3516 replace a quartz crystal oscillator?
Yes — this is a MEMS-based XO (Standard) that generates a clock output directly, so it replaces a quartz crystal plus oscillator circuit in one package. The LVDS output is a differential signal, so the receiver must be LVDS-compatible.
