Max supply current is 6.3 mA during active operation — low enough that the 4-SMD no-lead package (5.00 mm x 3.20 mm) does not require thermal vias or copper pour for heat spreading. Sourced through independent distribution on a quoted-to-order basis.","metaTitle":"DSC1001BI1-012.2880 MEMS Oscillator","metaDescription":"Microchip DSC1001BI1-012.2880 MEMS XO, 12.288 MHz, CMOS output, ±50 ppm stability, AEC-Q100, standby mode.

The part includes a Standby (Power Down) function. When disabled, the supply current drops to 15 µA max, and the output goes high-impedance — useful for battery-powered or sleep-mode systems."},{"question":"Is DSC1001BI1-012.2880 compatible with 3.3V systems?","answer":"Yes. The supply voltage range is 1.8V to 3.3V, so it works directly on a 3.3V rail without an external level translator or regulator."},{"question":"What is the closest pin-compatible alternative to DSC1001BI1-012.2880?","answer":"Within the Microchip DSC1001 family, other frequency variants share the same 4-SMD no-lead footprint and supply range. A same-frequency peer from a different MEMS oscillator family (e.g., SiTime SiT8008) would require comparing pinout and control logic — confirm the standby function and enable polarity against your schematic before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1001BI1-012.2880","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1001BI1-012.2880 when reusing this data.
