Why a MEMS oscillator instead of a quartz can
The supply range of 2.25 V to 3.6 V means the same BOM line works across a 3.3 V ECU and a 2.5 V sensor module.
AEC-Q100 qualified — the part has passed the full automotive stress suite: temperature cycling, HAST, ESD, and latch-up.
Package and board layout notes
6-SMD No Lead Exposed Pad, 7.00 mm x 5.00 mm body, 0.90 mm seated height. Useful for power-cycled clock trees in multi-rail systems; leave the pin floating or tie high if the oscillator must always run.
