Operating from 1.8V to 3.3V, the oscillator covers common logic rails without a dedicated regulator — useful for mixed-voltage designs where the same BOM line serves 1.8V and 3.3V domains. Housed in a 3.20mm x 2.50mm 4-SMD no-lead package with a seated height of 0.90mm, the footprint matches standard quartz oscillator pads, simplifying drop-in substitution on existing layouts.

Yes — the 3.20mm x 2.50mm 4-SMD no-lead package and CMOS output are footprint- and logic-compatible with standard 1.8432 MHz quartz oscillators. The MEMS resonator is inherently more shock- and vibration-tolerant than quartz, which is the main engineering trade-off.
Yes — the part includes a standby (power-down) function that reduces maximum supply current to 15 µA when disabled, allowing the system to gate the clock during sleep modes.
Yes — it carries AEC-Q100 rating, making it suitable for automotive-grade designs including under-hood and chassis-domain ECUs.
