Frequency stability is held to ±25 ppm across temperature and voltage, tight enough for a CAN-FD node or a 100BASE-T1 PHY reference without external trimming. ## Standby power-down for battery-conscious designs The 4-SMD, no-lead package (3.20 mm × 2.50 mm footprint, 0.90 mm seated height) fits tight layout zones under a shield can or alongside a BGA memory device.

This qualifies the oscillator for automotive-grade reliability testing including temperature cycling, ESD, and latch-up, making it suitable for under-hood and cabin applications."},{"question":"What supply voltage does DSC1001CI2-004.0000 accept?","answer":"The operating supply range is 1.8V to 3.3V. A single BOM line covers both 1.8V and 3.3V logic rails without a separate voltage-divider or LDO for the oscillator."},{"question":"What is the output type of DSC1001CI2-004.0000?","answer":"CMOS output. The 4 MHz square wave drives standard digital inputs — MCU clock pins, PHY reference inputs, or FPGA global clock buffers — without an external level translator."},{"question":"What is the closest pin-compatible alternative in the DSC1001 family?","answer":"The DSC1001 series shares the same 4-SMD no-lead footprint and pinout across all frequency variants. A different frequency within the series — for example DSC1001CI2-008.0000 for 8 MHz — is a direct drop-in replacement at the board level, requiring only a firmware clock-tree change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001CI2-004.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001CI2-004.0000 when reusing this data.
