Product details

Rated across -40 to 85°C with ±50 ppm frequency stability, it holds the clock edge within 4.5 ns of nominal over the full industrial-automotive temperature band.

Automotive-qualified — PPAP-ready for OEM auditors

AEC-Q100 listed in the ratings — this is not a 'capable' claim; it is a documented qualification that an OEM auditor will accept with PPAP documentation on file. The MEMS resonator structure inherently resists vibration and shock better than quartz, which is why automotive-grade MEMS oscillators are increasingly specified for engine-control and ADAS reference clocks.

Frequently asked questions

What is the exact frequency of the DSC1004AI1-090.0000T?

90 MHz — the '090.0000' in the order code is the nominal frequency.

Is the DSC1004AI1-090.0000T automotive qualified?

Yes, it carries an AEC-Q100 rating, meaning it has passed the automotive-grade reliability stress tests and is PPAP-documented for OEM supply chains.

How does this compare to other MEMS oscillators at 90 MHz?

The ±50 ppm stability and -40 to 85°C range are typical for a general-purpose MEMS XO. The AEC-Q100 qualification and wide 1.7-3.6 V supply are the differentiators — many industrial-grade MEMS oscillators skip the automotive stress screening or require a narrower supply.
