That means a processor core and its peripheral bus — or an FPGA fabric and its Ethernet MAC — can share one oscillator footprint instead of two, saving board space and reducing the BOM line count. The 2.25 V to 3.6 V supply range covers 2.5 V and 3.3 V logic rails without a separate LDO. A design running a 3.3 V FPGA core and a 2.5 V I/O bank can drop this oscillator on either rail and keep the same timing budget. The 6-VDFN package measures 2.50 mm x 2.00 mm with a 0.90 mm seated height — small enough for a space-constrained sensor module or a multi-layer backplane card. The 0.50 mm pitch pads require a fine-pitch solder stencil; a 4-mil stencil thickness with a 1:1 aperture-to-pad ratio is typical for this land pattern.","metaTitle":"DSC2311KI2-R0045 MEMS XO, 50 MHz & 24 MHz CMOS","metaDescription":"Microchip DSC2311KI2-R0045 dual-output MEMS oscillator: 50 MHz + 24 MHz, ±25 ppm stability, -40°C to 85°C, 2.25-3.6 V supply, 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":"±25ppm","Frequency - Output 1":"50MHz","Frequency - Output 2":"24MHz","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/6f97f7a94d0865985671f761ad599232.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the two output frequencies of the DSC2311KI2-R0045?","answer":"Output 1 is 50 MHz and output 2 is 24 MHz, both CMOS. The MEMS resonator generates both frequencies from a single die, so the two clocks are synchronous to the same reference."},{"question":"What supply voltage does the DSC2311KI2-R0045 need?","answer":"It operates from 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails. No external regulator is needed when the logic supply falls within that range."},{"question":"Is the DSC2311KI2-R0045 RoHS compliant?","answer":"The evidence does not explicitly state RoHS compliance.
