Supply voltage spans 1.7V to 3.6V, covering 1.8V, 2.5V, and 3.3V logic rails without an external regulator. Maximum supply current is 16.6 mA — the 75 MHz CMOS output drives standard digital loads directly. The MEMS resonator handles 50 g shock and 20 g vibration better than a quartz can; if the board sees a drop test or a machine-tool spindle, this oscillator keeps running.
Yes, if the circuit expects a CMOS-level clock input. A quartz crystal requires an external oscillator circuit (inverter, load caps); this MEMS XO outputs a full-swing CMOS signal directly, so it replaces both the crystal and the oscillator stage on the board. Pin-compatible with many standard 4-pin oscillators in the same 3.2 x 2.5 mm footprint — confirm the enable/disable logic matches your design.
Yes, it carries AEC-Q100 rating, which means it passed automotive-grade stress tests (temperature cycling, ESD, latch-up) and is PPAP-ready for production vehicle programs.
MEMS oscillators (like this DSC1001) use a silicon micro-electromechanical resonator instead of a quartz crystal. They typically offer better shock and vibration tolerance, faster start-up, and smaller package options. The trade-off: quartz can achieve tighter initial accuracy and lower phase noise at very high frequencies, but for a 75 MHz CMOS clock at ±10 ppm, the MEMS part is a drop-in replacement that survives harsher environments.
