Product details

MEMS XO with CMOS output and AEC-Q100 qualification

The 1.8V to 3.3V supply range lets it run from the same rail as the MCU or SoC without a separate regulator — useful when the BOM already has a 1.8V core supply or a 3.3V I/O rail.

Package footprint and supply flexibility

Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm max, the DSC1001DE2-012.0000T fits tight PCB real estate. The no-lead land pattern is straightforward for a standard reflow profile; no via-in-pad or buried-via fan-out required. Supply current maxes at 6.3 mA during active oscillation and drops to 15 µA when the standby (power-down) function is asserted. That 15 µA disable current is low enough to leave the oscillator powered from a battery-backed rail without draining the cell — relevant for always-on modules that need to wake on a timer.

Frequently asked questions

What is the output type of the DSC1001DE2-012.0000T?

CMOS output. The oscillator drives a standard CMOS load — no level translation needed if the downstream device accepts 1.8V to 3.3V logic levels.

Is the DSC1001DE2-012.0000T rated for automotive temperature range?

The part is AEC-Q100 qualified, but its specified operating temperature is -20°C to 70°C (commercial grade). For automotive applications requiring -40°C to +125°C, look at the DSC1001 family variants with the appropriate temperature suffix.

Can the DSC1001DE2-012.0000T operate from a 1.8V supply?

Yes. The supply voltage range is 1.8V to 3.3V, so it runs directly from a 1.8V rail without a separate regulator.

How does a MEMS oscillator differ from a quartz crystal oscillator?

A MEMS oscillator uses a silicon micro-electromechanical resonator instead of a quartz crystal. The MEMS resonator is fabricated with semiconductor processes, giving faster startup (microseconds vs milliseconds), better shock/vibration tolerance, and no crystal aging drift. The trade-off is typically tighter frequency stability (±25 ppm here) versus quartz's sub-±10 ppm in some high-end parts.
