Product details

40 MHz MEMS XO with AEC-Q100 — why it beats a quartz can

This is a MEMS-based oscillator, not a quartz crystal — the base resonator is a silicon MEMS structure, which gives it better shock and vibration immunity compared to a quartz tuning-fork or AT-cut crystal. Output is CMOS, so it drives logic inputs directly — no external level translation needed for 1.8V, 2.5V, or 3.3V rails within the 1.8V–3.3V supply range.

New designs can commit to this part without an early last-time-buy window. Sourced through independent distribution; quoted to order against the BOM line. Availability confirmed at RFQ — no stock-holding claim from this desk.

Standby power-down — 15 µA disable current

The Standby (Power Down) function pulls the output to high-impedance and drops supply current to 15 µA max — useful for battery-backed modules that need to shut the clock tree when the system sleeps. Active supply current is 7.2 mA max at 40 MHz — a fraction of what a canned quartz oscillator with a discrete buffer would consume.

Frequently asked questions

Can DSC1001AI1-040.0000T directly replace a standard 40 MHz quartz oscillator?

It can replace a standard 40 MHz quartz XO in the same 4-SMD footprint (7.0 x 5.0 mm) and with the same CMOS output. The MEMS resonator gives better shock/vibration tolerance than quartz, but the electrical interface is identical — supply 1.8V–3.3V, output CMOS, no external load caps needed.

Is DSC1001AI1-040.0000T qualified for automotive use?

Yes — it is rated AEC-Q100, the automotive IC qualification standard. For under-hood (125°C) environments, check the DSC1001 family's extended temp variants.
