Operating from 1.8V to 3.3V, the oscillator spans the three most common digital logic rails — no extra level translator or LDO needed for 1.8V or 3.3V domains.
Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint that matches many quartz oscillator pads, simplifying drop-in replacement.
Yes — the 4-SMD no-lead package (5.00 mm x 3.20 mm) and CMOS output are footprint- and logic-compatible with many 27 MHz quartz oscillators. The MEMS resonator offers better shock and vibration tolerance than quartz, and the ±50 ppm stability is equivalent to a standard quartz XO. Verify the supply voltage range (1.8V–3.3V) and enable polarity match your existing circuit.
Yes, it carries AEC-Q100 rating, meaning it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up. This qualifies it for under-hood and cabin electronics where standard commercial oscillators would not be accepted.
