Product details

Standby power-down and low-power sleep

During active operation the oscillator draws 7.2 mA max, so the standby savings are substantial in duty-cycled designs.

Package and footprint for hand-soldering

Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the DSC1001DI1-038.4000T is small enough for space-constrained PCBs but still hand-solderable with a fine-tip iron and some patience — the no-lead pads are accessible from the sides. The surface-mount package is supplied on Tape & Reel, ready for pick-and-place assembly.

Frequently asked questions

Is the DSC1001DI1-038.4000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, meaning it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up. This qualifies it for use in engine control, body electronics, and infotainment systems where the ambient temperature can reach 85°C.

Can the DSC1001DI1-038.4000T replace a traditional quartz crystal oscillator?

Yes — as a MEMS-based oscillator it is a drop-in replacement for a quartz XO in the same footprint and output logic. The MEMS resonator is inherently more shock and vibration tolerant than a quartz crystal, and the ±50 ppm stability covers most MCU and communication clock requirements.
