The DSC1001BI2-059.0000T: AEC-Q100 qualification means this part is qualified for automotive stress levels — suitable for engine control units, infotainment clusters, and ADAS sensor modules where vibration and thermal cycling are constant. The MEMS resonator replaces a quartz crystal blank, so there is no start-up uncertainty or crystal aging drift — the oscillator hits its rated frequency within microseconds of power-up and holds it through the supply range of 1.8V to 3.3V.
In active mode the oscillator draws 7.2 mA max at 59 MHz, which is typical for a MEMS XO at this frequency and well within the budget of a 3.3V rail from an LDO or switching regulator.
Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — this is the standard 5.0×3.2 mm oscillator footprint used across the DSC1001 family.
