This is the oscillator you spec when the board sees thermal cycling from -55°C soak to 125°C under-hood or downhole ambient, and a quartz XO would need a separate heater or risk failing to start. ## AEC-Q100 and the supply rail envelope Product status is Active — no EOL notice, no last-time-buy window.","metaTitle":"DSC1121BM1-008.0000 MEMS Oscillator 8 MHz CMOS AEC-Q100","metaDescription":"Microchip DSC1121BM1-008.0000 XO (Standard) MEMS oscillator, 8 MHz CMOS output, AEC-Q100 qualified, -55°C to 125°C.

The DSC1121BM1-008.0000 does not include spread spectrum — if your design requires EMI mitigation at the clock source, the DSC1122 is the functional alternative. Pin compatibility means a single PCB layout can accept either series by changing the BOM line."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121BM1-008.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121BM1-008.0000 when reusing this data.
