Frequency stability is held to ±25 ppm over the full temperature and voltage range, which keeps the clock edge jitter within the timing budget for 125 MHz serial links like Gigabit Ethernet or LVDS interfaces. ## Supply voltage flexibility and enable/disable control The 2.25V to 3.6V supply range lets the oscillator run directly off a 2.5V or 3.3V rail without an intermediate LDO — one less component on the BOM. An enable/disable pin lets the system gate the clock output; when disabled the supply current drops to 22 mA max, useful for power-cycled sensor nodes or multi-clock-domain power management. The part is available for new designs and production builds.","metaTitle":"DSC1121BI2-125.0000 – 125 MHz MEMS XO, CMOS, AEC-Q100","metaDescription":"Microchip DSC1121BI2-125.0000: 125 MHz MEMS oscillator, CMOS output, ±25 ppm 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":"0.197\\\" 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":"Is the DSC1121BI2-125.0000 AEC-Q100 qualified?","answer":"Yes, it carries AEC-Q100 ratings, meaning it meets automotive-grade reliability stress and temperature qualification."},{"question":"Does the DSC1121BI2-125.0000 have an enable/disable function?","answer":"Yes, the function is Enable/Disable.
