The DSC1122 series typically offers a different output type or feature set — confirm the output (CMOS vs LVDS vs HCSL) and the enable/disable polarity for your BOM position before substituting. The DSC1121DI5-034.3680 is a standard CMOS XO with active-high enable."},{"question":"Can the DSC1121DI5-034.3680 replace a standard quartz oscillator?","answer":"Yes — the 6-SMD no-lead footprint matches the common quartz oscillator land pattern, and the CMOS output is compatible with most clock inputs. The MEMS part does not require external load capacitors and offers better shock and vibration immunity than quartz. Confirm the supply voltage (2.25V-3.6V) and the enable/disable function match the original oscillator's pinout."},{"question":"Is the DSC1121DI5-034.3680 compatible with a 3.3V supply?","answer":"Yes — the supply range is 2.25V to 3.6V, so a 3.3V rail is within spec. The CMOS output swings rail-to-rail, so the logic-high level matches 3.3V CMOS inputs directly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121DI5-034.3680","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121DI5-034.3680 when reusing this data.
