148.5 MHz MEMS oscillator with automotive qualification
AEC-Q100 qualification puts this part in the automotive-grade bin — suitable for engine control units, ADAS camera modules, and infotainment head units where the ambient temperature cycles through -40°C and sees sustained 85°C under the dash.
The wide supply range from 2.25V to 3.6V means a single DSC1121CI2-148.5000 can run from a 3.3V or 2.5V rail without a dedicated LDO — useful for mixed-voltage systems where the core SoC runs 1.8V and the I/O bank is 3.3V.
Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — this is a standard 3.2 x 2.5 mm ceramic oscillator footprint, so the PCB pad layout and solder stencil aperture are well-documented and easily sourced. Surface-mount assembly with no leads means the thermal pad is the bottom of the package; the reflow profile follows standard lead-free solder recommendations for ceramic SMD oscillators.
