Disable current max is 22 mA, compared to 35 mA when running — not a deep-sleep saving, but enough to drop the thermal contribution on a dense board. The supply range spans 2.25V to 3.6V, so the same order code serves a 2.5V FPGA bank and a 3.3V SoC clock input without a second line item. Microchip lists the DSC1121CI2-014.3181 as Active. No NRND flag, no EOL notice — this part is safe to design in for production runs that span multiple years.","metaTitle":"DSC1121CI2-014.3181 MEMS Oscillator 14.3181 MHz CMOS -","metaDescription":"DSC1121CI2-014.3181 XO (Standard) MEMS oscillator, 14.3181 MHz CMOS output, 2.25V-3.6V supply, -40°C~85°C, 6-VDFN.

That gives it better shock and vibration tolerance than a traditional crystal oscillator, and it eliminates the quartz start-up time. The output is standard CMOS, so it drops directly into a 14.3181 MHz clock input on most SoCs and FPGAs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CI2-014.3181","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CI2-014.3181 when reusing this data.
