However, pin assignments and enable logic differ — always compare the datasheet's pinout before dropping one into a board designed for the other."},{"question":"What does the standby (power-down) function do on this oscillator?","answer":"The standby function disables the output and puts the oscillator into a low-power state drawing 15 µA max. It is controlled by the enable pin — pulling it low shuts down the output; pulling it high or leaving it floating enables normal operation."},{"question":"Is the DSC1001DE1-020.0000 suitable for automotive environments?","answer":"Yes — it carries an AEC-Q100 rating, which qualifies it for automotive-grade applications. The -20°C to 70°C temperature range suits cabin or climate-controlled modules, not under-hood or exterior locations where -40°C to 125°C is required."},{"question":"How does the DSC1001DE1-020.0000 compare to the DSC1001DI1-020.0000?","answer":"Both share the same 20 MHz frequency, CMOS output, MEMS resonator, and DSC1001 series. The key difference is the operating temperature range: the DE1 suffix covers -20°C to 70°C, while the DI1 suffix covers -40°C to 85°C. Choose the DI1 variant if your application sees sub-zero or elevated temperatures outside the DE1's range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001DE1-020.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001DE1-020.0000 when reusing this data.
