Product details

31.25 MHz MEMS oscillator with AEC-Q100 qualification

Rated AEC-Q100, this part is qualified for automotive applications where reliability under temperature cycling and vibration is required — suitable for engine control units, ADAS sensors, and infotainment modules. The Enable/Disable function lets the system gate the output clock, dropping supply current to 15 µA (max) when the oscillator is disabled — useful for power-sensitive sleep modes in battery-backed or automotive always-on domains.

Supply voltage flexibility and current budget

Maximum supply current is 7.2 mA at full load, keeping the thermal footprint low in the compact 3.20 mm × 2.50 mm 4-SMD package.

Frequently asked questions

Can DSC1001CI2-031.2500 replace a standard 31.25 MHz quartz oscillator?

Yes — it is a drop-in replacement for a 31.25 MHz quartz oscillator in the same 4-SMD footprint. The MEMS resonator offers better shock and vibration tolerance compared to quartz, and the ±25 ppm stability is equivalent to a standard quartz XO. The Enable/Disable function may require a pull-up or pull-down on the enable pin if the original quartz part did not have one.
