Product details

AEC-Q100 qualified MEMS oscillator – 31.25 MHz, ±25 ppm

That ±25 ppm window covers the full temperature spread without a separate TCXO — the MEMS die compensates internally. Supply voltage range is 2.25V to 3.6V, so the oscillator runs from a single 2.5V or 3.3V rail without a regulator.

Active production – no last-time-buy window

Lifecycle status is Active.

Package is 6-SMD, No Lead, 3.20 mm x 2.50 mm body, 0.90 mm seated height. Pin compatible with standard 6-pin oscillators in the same footprint (6-SMD, 3.2 x 2.5 mm). Confirm the enable polarity and supply voltage match the existing BOM — the logic levels are CMOS, not LVDS or HCSL.
