That certification is the gate for under-hood or cabin-domain designs where a standard commercial oscillator would require a waiver. Operating from 1.8V to 3.3V, this single oscillator covers the three most common digital rails — a mixed-voltage design can use the same BOM line across 1.8V, 2.5V, and 3.3V domains. That 420:1 ratio makes it practical to gate the clock off during system sleep without a separate load switch.","metaTitle":"DSC1001BI1-012.2880T MEMS XO – 12.288 MHz, AEC-Q100, Active","metaDescription":"Microchip DSC1001BI1-012.2880T: 12.288 MHz MEMS oscillator, CMOS output, ±50 ppm stability, AEC-Q100, -40 to 85°C.

That qualification covers the -40 to 85°C temperature range and includes the reliability stress tests (temperature cycling, ESD, latch-up) required for automotive-grade components. It fits under-hood and cabin-domain designs without a waiver."},{"question":"Can DSC1001BI1-012.2880T replace a failed 12.288 MHz crystal oscillator?","answer":"Yes, if the original was a 12.288 MHz CMOS-output oscillator in a 5.0 x 3.2 mm 4-pin no-lead package. The MEMS resonator eliminates the external load capacitors and the crystal startup delay.
