This replaces multiple discrete oscillators on the BOM, saving board space and reducing procurement line items. The supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V rails common in FPGA and SoC designs — no extra LDO needed for the oscillator alone. Frequency stability is ±50 ppm, adequate for 1000BASE-T Ethernet, USB 2.0, and general-purpose clock trees. For precision RF or 10G+ SerDes, a tighter ±25 ppm or TCXO would be the better call. The 20-VFQFN exposed-pad package (5.00mm x 3.20mm, 0.90mm height) requires a thermal via pattern under the pad for proper solder-joint reliability — standard for this class.","metaTitle":"DSC400-3111Q0088KI1 MEMS XO – Quad Output, Active","metaDescription":"Microchip DSC400-3111Q0088KI1 XO (Standard) MEMS oscillator: 4 outputs (148.25 MHz, 12/24 MHz, 25/100 MHz, 148.25 MHz), ±50 ppm, -40°C to 85°C, 2.25-3.6V.","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":"LVCMOS, LVDS","Series":"DSC400","Package":"Tube","Function":"Enable/Disable","Base Resonator":"MEMS","Package / Case":"20-VFQFN Exposed Pad","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":"DSC400","Frequency Stability":"±50ppm","Frequency - Output 1":"148.25MHz","Frequency - Output 2":"12MHz, 24MHz","Frequency - Output 3":"25MHz, 100MHZ","Frequency - Output 4":"148.25MHz","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2723b9747a2eae277fa05951882c31f9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest alternative if the DSC400-3111Q0088KI1 is unavailable?","answer":"Within the DSC400 family, any factory-programmed variant with the same 20-VFQFN package and supply voltage range is footprint-compatible — the frequency plan is the only difference.
