Unlike quartz-based oscillators, the MEMS resonator offers better resistance to shock and vibration, and a faster startup time — relevant for avionics, downhole instrumentation, and satellite payloads where the board sees wide thermal cycling. ## Supply voltage and output drive The supply range spans 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an external regulator — one less part on the BOM. Maximum supply current is 35 mA when enabled, and 22 mA when disabled via the Enable/Disable function — the disable current is still present because the MEMS resonator and PLL remain powered, so a true power-down requires switching the supply rail. ## Package and board layout fit Housed in a 6-SMD, no-lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — a standard footprint that matches many 5x3.2 mm oscillators, simplifying a drop-in replacement if the BOM changes. Surface-mount assembly with no exposed leads means the package is self-aligning during reflow; the 0.90mm height keeps it below most enclosure standoffs. Sourced through independent distribution; quoted to order against the BOM quantity.","metaTitle":"DSC1121BM2-025.0000T MEMS Oscillator – Microchip, 25 MHz","metaDescription":"DSC1121BM2-025.0000T XO (Standard) from Microchip Technology. 25 MHz CMOS output, ±25 ppm stability, 2.25V-3.6V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1121","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Enable/Disable","Frequency":"25 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC1121","Frequency Stability":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-55°C~125°C","Current - Supply (Max)":"35mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the DSC1121BM2-025.0000T have an enable/disable function?","answer":"Yes, it includes an Enable/Disable function.
