The 33.333 MHz CMOS output and 3.3V supply match most quartz XO footprints. The MEMS base resonator provides faster startup and better shock/vibration tolerance than quartz, with no external load capacitors needed."},{"question":"What is the difference between this MEMS oscillator and a standard crystal oscillator?","answer":"A MEMS oscillator integrates the resonator and driver in one silicon die, eliminating the quartz crystal blank and its external load caps. The DSC1033 series offers ±50 ppm stability without the aging drift of quartz, and draws 3 mA active vs. typical quartz XO current of 5–15 mA at the same frequency."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033BI1-033.3330","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033BI1-033.3330 when reusing this data.
