If your application runs at 105°C ambient, this part is not rated for that — you would need the extended-temperature variant in the DSC1121 family. ## MEMS resonator vs quartz — what changes on the board That means no load-capacitance matching, no start-up time uncertainty, and no drive-level sensitivity — the oscillator starts in microseconds and holds frequency across vibration and supply ripple. For a replacement of a standard 8 MHz quartz oscillator, the DSC1121BI2-008.0000T is a direct drop-in: same 8 MHz CMOS output, same 2.25V to 3.6V supply range, same 6-VDFN footprint. A typical quartz XO at this price point might spec ±50 ppm or ±100 ppm; the MEMS part holds tighter without external trimming.","metaTitle":"DSC1121BI2-008.0000T MEMS XO 8 MHz CMOS AEC-Q100 Active","metaDescription":"DSC1121BI2-008.0000T is an active-production MEMS oscillator from Microchip Technology. 8 MHz CMOS output, ±25 ppm stability, AEC-Q100 qualified.","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":"AEC-Q100","Function":"Enable/Disable","Frequency":"8 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-VDFN","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":"-40°C ~ 85°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":"Can DSC1121BI2-008.0000T replace a standard 8 MHz quartz oscillator?","answer":"Yes.
