The 2.25V to 3.6V supply range covers common logic rails (2.5V, 3.0V, 3.3V) without an external LDO — the enable/disable function lets the system shut off the oscillator and drop supply current from 35mA max to 22mA max.","metaTitle":"DSC1121DM1-033.3333 MEMS XO 33.3333 MHz CMOS -55°C to 125°C","metaDescription":"Active production MEMS oscillator, 33.3333 MHz CMOS output, ±50ppm stability, 2.5x2.0mm 6-SMD package.

The trade-off is that the ±50ppm stability is typical for a standard XO; for tighter stability (e.g., ±25ppm or ±10ppm) a TCXO or OCXO would be needed, but those come in larger packages and higher cost."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121DM1-033.3333","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121DM1-033.3333 when reusing this data.
