The DSC1121CI2-020.0000T: Its AEC-Q100 qualification means it is production-ready for automotive-grade systems — under-hood ECU, cabin infotainment, or ADAS camera modules where a quartz oscillator's shock sensitivity or temperature drift would risk timing margin.
Supply voltage and current budget for BOM planning
Operating from 2.25 V to 3.6 V, this oscillator spans both 2.5 V and 3.3 V logic rails without needing a dedicated LDO — simplifies the power tree on a mixed-voltage board.
Package footprint and layout fit
Housed in a 3.20 mm x 2.50 mm 6-SMD package (0.90 mm seated height), the footprint is compatible with standard 3.2 x 2.5 mm oscillator pads — no special via-in-pad or buried via required for a 2-layer board.
