The LVDS signalling keeps jitter low for high-speed serial interfaces such as Gigabit Ethernet, PCIe, and SerDes reference clocks, where a quartz oscillator's startup time or vibration sensitivity can cause link retraining. AEC-Q100 qualification extends the part's suitability to automotive domains — infotainment head units, camera modules, and ADAS sensor fusion boards that must hold clock integrity under engine vibration and thermal cycling. The MEMS resonator inherently withstands 50,000 g shock and 70 g vibration, a reliability margin quartz cannot match without additional packaging. The supply voltage range spans 2.25 V to 3.63 V, covering 2.5 V and 3.3 V rails common in mixed-signal designs. This is a design-in grade part — no last-time-buy window to manage, no forced migration to a successor. The 6-SMD, no-lead exposed-pad package is a standard 7.0 mm × 5.0 mm footprint shared across the DSC1123 family, simplifying second-source qualification if needed.","metaTitle":"DSC1123AE2-300.0000 Microchip MEMS XO 300 MHz LVDS AEC-Q100","metaDescription":"DSC1123AE2-300.0000: Microchip DSC1123 series MEMS XO, 300 MHz LVDS output, ±25 ppm stability, AEC-Q100, 2.25V-3.63V supply.

However, the MEMS resonator offers faster startup, higher shock/vibration tolerance, and better long-term reliability than quartz. Confirm the output type (LVDS) and supply voltage range (2.25 V–3.63 V) match your existing quartz oscillator's specifications before substituting."},{"question":"What is the difference between MEMS and quartz oscillators?","answer":"MEMS oscillators use a silicon micro-electromechanical resonator instead of a quartz crystal. The MEMS resonator in the DSC1123 series provides inherent immunity to shock and vibration, faster startup time, and lower sensitivity to supply noise compared to quartz. Frequency stability (±25 ppm,) is comparable to standard quartz XOs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123AE2-300.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123AE2-300.0000 when reusing this data.
