But the MEMS resonator inside has different startup behaviour and shock tolerance. The 6-VDFN footprint (2.50 mm x 2.00 mm) is common for MEMS oscillators; verify the pinout matches your existing quartz oscillator's land pattern before committing the board spin."},{"question":"How does DSC2311KI2-R0003T compare to similar SiTime oscillators?","answer":"Both are MEMS-based XOs with CMOS outputs in similar small packages. The key difference is the supply range: the DSC2311KI2-R0003T spans 2.25 V to 3.6 V, while many SiTime parts are fixed to 2.5 V or 3.3 V only. That wider range simplifies BOM consolidation across multiple voltage domains."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC2311KI2-R0003T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC2311KI2-R0003T when reusing this data.
