What the AEC-Q100 rating means for this oscillator
The DSC8001AI2T carries an AEC-Q100 qualification — this is the automotive IC stress test standard covering temperature grade, reliability, and PPAP. For a MEMS-based XO, that qualification means the resonator and ASIC survive the thermal shock, vibration, and extended temperature cycles of an under-hood or chassis-mounted ECU.
The maximum supply current is 12.2 mA at the highest frequency and voltage, which is within the budget of a typical LDO or switching regulator. This matters for battery-backed modules or sleep-mode ECUs where the oscillator's quiescent draw must stay below the leakage floor of the power switch.
Programming and frequency range
This part is a blank (user-programmable) device — the factory ships it without a fixed frequency.
