For a second-source option within the same family, the base product number DSC1001 covers multiple frequency and stability variants.","metaTitle":"DSC1001BI1-125.0000 125 MHz MEMS XO, AEC-Q100, CMOS","metaDescription":"Microchip DSC1001BI1-125.0000: 125 MHz MEMS oscillator, AEC-Q100 qualified, CMOS output, 1.8V-3.3V supply, -40°C to 85°C.

The DSC1001 series itself offers multiple frequency and stability variants under the same base product number DSC1001. For a same-frequency alternative, confirm the package (4-SMD, 5.0x3.2 mm), supply voltage range, and CMOS output — many quartz and MEMS oscillators in this footprint are functional equivalents but may lack the AEC-Q100 qualification."},{"question":"What is the function of the standby (power down) pin?","answer":"The standby function disables the output and reduces current consumption to 15 µA max, allowing the oscillator to be gated off during system sleep modes while maintaining a fast wake-up time typical of MEMS devices."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001BI1-125.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001BI1-125.0000 when reusing this data.
