AEC-Q100 rated, it is qualified for automotive environments spanning -40°C to 85°C — suitable for under-hood ECUs, ADAS reference clocks, and infotainment modules where quartz oscillators may not survive the vibration profile. CMOS output and a supply range of 2.25V to 3.6V mean this oscillator can be powered from a 2.5V or 3.3V rail directly — no extra level translator needed for the clock line. Frequency stability is ±25ppm, tight enough for 125 MHz Ethernet PHY reference clocks or FPGA transceiver PLLs without external trimming. ## 6-SMD no-lead — layout footprint and rework considerations Housed in a 6-SMD, No Lead package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the footprint is standard for this form factor and matches many 7x5 mm MEMS oscillator pads. Surface-mount assembly with no leads means the part is self-aligning during reflow; the package outline is large enough that orientation marking is clear under a loupe — no lab bench needed to confirm placement.","metaTitle":"DSC1121NI2-125.0000 MEMS XO, 125 MHz CMOS, AEC-Q100, Active","metaDescription":"Microchip DSC1121NI2-125.0000: XO (Standard) MEMS oscillator, 125 MHz CMOS output, 2.25V-3.6V supply, ±25ppm stability, -40°C to 85°C, AEC-Q100.","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":"Tube","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"125 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","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":"What is the output type and voltage range of DSC1121NI2-125.0000?","answer":"The output is CMOS, and the supply voltage range is 2.25V to 3.6V.
