This is a standard output-enable control, not a shutdown — the internal MEMS resonator and PLL remain powered, so restart latency is minimal."},{"question":"What is the difference between DSC1121 and DSC1122?","answer":"The DSC1121 is a standard MEMS XO with CMOS output. The DSC1122 is a different series within the same family — the key parametric difference is typically output type or supply voltage range. For a pin-compatible alternative within the DSC1121 family, the base product number is DSC1121; other frequency variants share the same 6-SMD footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121BE2-100.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121BE2-100.0000 when reusing this data.
