Frequency stability is ±50 ppm, tight enough for CAN, LIN, and most MCU clock domains without external compensation. ## MEMS vs. quartz — why this oscillator avoids crystal aging drift The ceramic 4-SMD package (, 3.20mm x 2.50mm) is a drop-in footprint compatible with many quartz crystal oscillators, but the MEMS die eliminates the need for a separate quartz blank and its associated aging curve.","metaTitle":"DSC1001CI1-012.0000T MEMS Oscillator 12 MHz AEC-Q100","metaDescription":"Microchip DSC1001CI1-012.0000T MEMS XO, 12 MHz, CMOS, 1.8V-3.3V, AEC-Q100, -40°C to +85°C, 4-SMD.

The DSC1001CI1-012.0000T is a MEMS-based XO (standard) with the same 12 MHz frequency and CMOS output as a typical quartz crystal oscillator. The 4-SMD footprint (, 3.20mm x 2.50mm) is compatible with many standard quartz oscillator footprints. The key difference is that the MEMS resonator avoids crystal aging drift and is more shock-tolerant. Confirm the supply voltage range (1.8V to 3.3V,) and frequency stability (±50 ppm,) match your application before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI1-012.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI1-012.0000T when reusing this data.
