6-SMD no-lead package, 2.50 mm × 2.00 mm body, 0.90 mm seated height — this is the standard 6-pin QFN footprint for MEMS oscillators. The no-lead construction keeps the parasitic inductance low at 125 MHz. For a shared clock tree, this lets you gate the oscillator without a separate buffer.
Yes — the ratings field lists AEC-Q100 qualification. This means the part passed automotive-grade reliability stress (temperature cycling, ESD, latch-up) and is suitable for under-hood or cabin electronics where the ambient temperature can reach 125°C.
CMOS output — single-ended, rail-to-rail swing, compatible with standard CMOS and TTL inputs at the supply voltage.
