Rated AEC-Q100, this oscillator passes the automotive-grade stress suite: temperature cycling, ESD, and extended life tests. That qualification is the main differentiator from a standard quartz oscillator — the MEMS die and plastic package are built to survive under-hood thermal shock and vibration without the failure modes (activity dips, spurs) that quartz can exhibit in harsh environments. For a non-automotive BOM, a quartz XO may be cheaper; for an AEC-Q100 bill, the DSC1001DI2-004.0960 is the correct entry.
The supply voltage range is 1.8 V to 3.3 V, so the same part works across 1.8 V MCU banks and 3.3 V peripheral rails without a level shifter.
