The 2.25V to 3.6V supply range lets it run directly from a 3.3V or 2.5V rail without an intermediate LDO. Frequency stability is ±25 ppm, which is tight enough for a CAN bus or LIN node reference without needing an external trim capacitor. ## Enable/Disable function for power sequencing This is useful for sleep-mode power budgets in battery-backed automotive modules. The 6-SMD no-lead package (3.20 mm x 2.50 mm, 0.90 mm seated height) is a standard MEMS oscillator footprint — it drops into the same land pattern as many quartz-based XOs, making it a straight swap on existing boards. Because this is a MEMS oscillator, there is no quartz supply-chain constraint; the base resonator is a semiconductor MEMS die, which follows the same fab capacity as the rest of Microchip's portfolio.","metaTitle":"DSC1121CI2-012.0000 MEMS XO – 12 MHz CMOS, AEC-Q100, Active","metaDescription":"Microchip DSC1121CI2-012.0000: MEMS-based XO, 12 MHz CMOS output, AEC-Q100 qualified, -40°C to 85°C, 2.25V-3.6V supply.

The DSC1121CI2-012.0000 is rated AEC-Q100, which means it has been qualified to the automotive stress tests (temperature cycling, ESD, latch-up, and early-life failure rate) required for PPAP submission. The temperature grade covers -40°C to 85°C."},{"question":"Can the DSC1121CI2-012.0000 replace a quartz crystal oscillator in an existing design?","answer":"It is a functional replacement for a standard 12 MHz XO with CMOS output in a 3.2 mm x 2.5 mm footprint. However, because it is MEMS-based, the startup time and jitter profile differ from quartz — confirm the downstream PLL or timing margin accepts a MEMS source. No pinout change is required for the 6-SMD no-lead package."},{"question":"How do I order the DSC1121CI2-012.0000 or get current pricing?","answer":"The part is active and available for order.
