The DSC1121AI2-048.0000T: AEC-Q100 qualification means this part is production-tested for automotive reliability — suitable for under-hood ECUs, ADAS processing modules, and infotainment clock domains where quartz oscillators might fail under vibration or thermal shock.
The oscillator operates from 2.25 V to 3.6 V, covering common logic rails without an external regulator.
Package and footprint planning
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the DSC1121AI2-048.0000T fits standard oscillator footprints and reflow profiles for 0.5 mm pitch pads.
