Operating from 1.8V to 3.3V, the oscillator covers the common logic rails used in automotive ECUs and industrial controllers — no external level translator needed when the MCU runs at 3.3V or 1.8V.
Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the footprint matches standard 3.2 x 2.5 mm oscillator pads — no layout change from quartz equivalents.
Yes, the part is rated AEC-Q100, which qualifies it for automotive-grade temperature and reliability stress testing. This covers under-hood and cabin applications where standard commercial oscillators would not be accepted.
It is a standard XO with CMOS output at 18.432 MHz. CMOS logic levels are compatible with most MCU clock inputs without external conditioning.
