The MEMS resonator replaces the quartz crystal — no load-capacitance matching, no start-up margin to calculate, and no crystal aging drift to budget. ## Supply range and enable/disable function Operating from 2.25V to 3.6V, the oscillator spans 2.5V and 3.3V logic rails without a separate regulator. The Enable/Disable function lets the system gate the clock — pulling the enable pin low drops supply current from 35 mA max to 22 mA max, useful for power-sensitive designs that shut down unused peripherals. ## Active lifecycle — design-in ready Microchip lists the DSC1121CI1-025.0000T as Active.","metaTitle":"DSC1121CI1-025.0000T MEMS Oscillator","metaDescription":"Microchip DSC1121CI1-025.0000T MEMS XO, 25 MHz CMOS output, ±50 ppm stability, -40°C to 85°C, 2.25V-3.6V supply.

The MEMS resonator eliminates the need for external load capacitors and offers better shock/vibration tolerance. Confirm the footprint matches your layout: 3.20mm x 2.50mm, 0.90mm seated height. No pin-for-pin quartz equivalent is listed by Microchip; the DSC1121 series is a MEMS-native design."},{"question":"How can I order DSC1121CI1-025.0000T or request a quote?","answer":"The part is Active and available through independent distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1121CI1-025.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1121CI1-025.0000T when reusing this data.
