The MEMS resonator in this part does not have a crystal blank that can crack or change mode, so it holds frequency through thermal cycling and mechanical shock — relevant for avionics, downhole logging, and satellite bus clocks where a quartz failure would be a mission event. The supply range spans 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an external regulator. Housed in a 6-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The no-lead footprint has a large ground pad underneath — the datasheet's recommended layout uses via-in-pad to the ground plane for thermal relief and to keep the MEMS die's substrate at a stable temperature. The 0.90 mm height fits under many mezzanine boards or within a 1.0 mm keep-out zone.","metaTitle":"DSC1121BM1-024.0000T MEMS Oscillator – Microchip, 24 MHz","metaDescription":"Active Microchip DSC1121BM1-024.0000T XO (Standard) with MEMS resonator, 24 MHz CMOS output, ±50 ppm stability, -55°C to 125°C.","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":"24 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":"±50ppm","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":"$1.8000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4ad75d2f22fe92055f4a953b00c76a2c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output type and frequency of the DSC1121BM1-024.0000T?","answer":"It is a standard XO with a CMOS output at 24 MHz.
