Product details

Its AEC-Q100 qualification means it passed the automotive-grade stress and reliability tests — this is the part to specify when the BOM calls for a timing source that survives under-hood or cabin temperature swings without the failure modes of a quartz crystal.

Active lifecycle — available for design-in now

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. Maximum operating current is 7.2 mA — a low-power draw that keeps the thermal budget clean on a densely populated board.

Frequently asked questions

Where can I buy DSC1001AI2-027.0000T and how do I get a price?

No stock-holding claim is made — availability is verified per inquiry.

Can DSC1001AI2-027.0000T be used in automotive applications?

Yes — it is AEC-Q100 qualified, which means it passed the automotive-grade stress and reliability tests.

What is the standby function on DSC1001AI2-027.0000T?

The standby (power-down) function disables the output and reduces current consumption to 15 µA max. Pulling the enable pin low puts the oscillator into this low-power state; pulling it high resumes normal operation.

What is the difference between DSC1001AI2-027.0000T and DSC1001DI2-027.0000T?

Both are 27 MHz MEMS XOs in the DSC1001 series with the same package and ±25 ppm stability. The suffix difference (AI2 vs DI2) typically indicates a different temperature range or output drive strength variant — confirm the exact ordering code against your BOM's operating temperature and load capacitance requirements.

Can DSC1001AI2-027.0000T replace a quartz oscillator?

Yes — it is a drop-in MEMS replacement for a standard 27 MHz quartz XO in the same 7.00 mm x 5.00 mm footprint. MEMS oscillators offer better shock and vibration tolerance than quartz and do not require a load capacitor on the output.
