Temperature range and frequency stability

The ±25 ppm hold over temperature is tight enough for most MCU and communication PHY reference clocks — a 33 MHz signal drifts less than 825 Hz across the full range, keeping the PLL in lock without re-centering.

Housed in a 4-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm. The 4-pin no-lead footprint is common for small oscillators — the pad layout matches industry-standard 5.0 x 3.2 mm MEMS and quartz XO footprints, so a board designed for a quartz part can take this MEMS part without a layout change.

Frequently asked questions

Is DSC1004BI2-033.0000T AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, which means it has passed the automotive-grade qualification tests — temperature cycling, ESD, latch-up, and early-life failure rate — required for deployment in automotive ECUs and modules.

What is the difference between MEMS and crystal oscillators?

A MEMS oscillator uses a silicon micro-electromechanical resonator instead of a quartz crystal. The MEMS structure is inherently more resistant to shock and vibration, and the oscillator IC compensates for temperature drift electronically rather than relying on the crystal's cut angle. For the DSC1004BI2-033.0000T, the practical difference is better reliability in high-vibration environments like engine bays or industrial machinery.

What is the output type and frequency of DSC1004BI2-033.0000T?

It is a standard XO with CMOS output at 33 MHz. CMOS output is compatible with most digital logic families — no level translation needed for 1.8V, 2.5V, or 3.3V logic.
