Product details

Automotive-grade MEMS oscillator for timing-sensitive designs

Its AEC-Q100 qualification makes it suitable for automotive cabin and chassis-domain applications where quartz oscillators may suffer from vibration-induced frequency shifts or cold-start drift.

Operating from 1.8V to 3.3V, this oscillator can be shared across a mixed-voltage board — a 3.3V MCU and a 1.8V FPGA can use the same BOM line.

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, the DSC1001AI2-014.7456 fits the standard 7x5 mm oscillator footprint.

The MEMS resonator construction means no quartz crystal inventory management — store the reels dry per standard MSL handling.

Frequently asked questions

Is DSC1001AI2-014.7456 compatible with 3.3V logic?

Yes. The supply voltage range of 1.8V to 3.3V covers 3.3V logic families directly. The CMOS output swings rail-to-rail, so it drives 3.3V inputs without level translation.

Can DSC1001AI2-014.7456 replace a 14.7456 MHz quartz oscillator?

Functionally yes — same frequency, same CMOS output, same 7x5 mm footprint. The MEMS base resonator offers better vibration and shock resistance than quartz, which is why it carries AEC-Q100 qualification. No pinout change is needed if the original quartz oscillator used the standard 4-pad SMD layout.
