Product details

The DSC1001DI1-033.3000T: This is a MEMS-based XO (Standard) running at 33.3 MHz with a CMOS output — no quartz crystal inside, just a silicon resonator sealed in a 4-SMD, no-lead package. Supply voltage range is 1.8V to 3.3V, so it runs off a common 3.3V rail or a low-voltage 1.8V core supply without a separate regulator.

Standby power-down for low-power operation

That 480× reduction means the oscillator stops drawing meaningful power in sleep mode — useful for battery-backed modules or intermittent-duty controllers where every microamp matters.

Frequently asked questions

Is the DSC1001DI1-033.3000T suitable for automotive applications?

Yes — it carries an AEC-Q100 rating, which means it passed the automotive-grade qualification for temperature, reliability, and PPAP.

Can DSC1001DI1-033.3000T be used as a drop-in replacement for a quartz oscillator?

In most cases, yes, as long as the original quartz oscillator had a CMOS output, ran on 1.8V to 3.3V, and fit the same 2.5mm x 2.0mm 4-SMD footprint. The MEMS resonator is more shock- and vibration-tolerant than quartz, so it is a net upgrade in rugged environments. Verify the enable polarity and standby behaviour match your circuit.
