Rated AEC-Q100, this part is qualified for automotive applications — the MEMS resonator and CMOS drive stage are tested to the stress and reliability requirements of the automotive IC qualification standard. ## Supply flexibility and standby power The supply voltage range spans 1.8V to 3.3V — a single BOM line covers 1.8V, 2.5V, or 3.3V clock domains without a separate regulator or level translator. A standby (power-down) function drops the supply current to 15 µA max, letting the oscillator gate its own power draw when the downstream logic is idle. Active current draw is 7.2 mA max at 66 MHz, which keeps the thermal contribution low in a sealed 4-SMD package. ## Active lifecycle and sourcing Sourced through independent distribution, quoted to order against the BOM quantity.","metaTitle":"DSC1001CE1-066.0000T – Microchip MEMS XO, 66 MHz, CMOS","metaDescription":"Active Microchip DSC1001 MEMS oscillator, 66 MHz, CMOS output, ±50 ppm stability, 1.8V-3.3V supply, AEC-Q100 qualified.

The standby function disables the output and drops the supply current to 15 µA max, which is useful for battery-powered or intermittent-operation systems."},{"question":"What is the difference between DSC1001CE1-066.0000T and standard quartz oscillators?","answer":"The DSC1001 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators typically offer faster startup, better shock and vibration tolerance, and a smaller footprint, while quartz oscillators may have lower phase noise in some frequency bands. The AEC-Q100 qualification on this part is a key differentiator for automotive use."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CE1-066.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CE1-066.0000T when reusing this data.
