Supply voltage spans 2.25 V to 3.6 V, so the same oscillator runs on a 2.5 V or 3.3 V rail without a level translator. ## Industrial-temperature oscillator in a small footprint The 6-VDFN package measures 2.50 mm x 2.00 mm with a 0.90 mm height — it sits on a small PCB real estate, but the 0.50 mm pitch pads require a controlled soldering profile and careful stencil design to avoid bridging. For a true power-down, the supply rail itself must be switched. Microchip lists the DSC2311KI1-R0054 as Active. The base product number DSC2311 covers a family of dual-output MEMS oscillators with different frequency and stability options. If the BOM later needs a different output frequency, a sibling within the DSC2311 family shares the same 6-VDFN footprint and supply range.","metaTitle":"DSC2311KI1-R0054 MEMS XO – 6.78 MHz CMOS, 6-VDFN, Active","metaDescription":"Microchip DSC2311KI1-R0054 XO (Standard) MEMS oscillator, dual 6.78 MHz CMOS outputs, ±50 ppm stability, -40°C to 85°C, 6-VDFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Height":"0.035\\\" (0.90mm)","Output":"CMOS","Series":"DSC2311","Package":"Tube","Function":"Enable/Disable","Base Resonator":"MEMS","Package / Case":"6-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC2311","Frequency Stability":"±50ppm","Frequency - Output 1":"6.78MHz","Frequency - Output 2":"6.78MHz","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"-","Current - Supply (Disable) (Max)":"23 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/56defa9c1eabe62796c315fa0425ae77.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the DSC2311KI1-R0054 have an enable/disable function?","answer":"Yes. The function is listed as Enable/Disable. Pulling the enable pin low disables the CMOS outputs, reducing supply current to 23 mA max. The internal MEMS resonator and PLL remain active, so the oscillator resumes full operation within a few microseconds when re-enabled."},{"question":"What is the output type of the DSC2311KI1-R0054?","answer":"The output is CMOS.
