Maximum draw is 60 mA typical when enabled; the disable function drops it to 23 mA max — useful for power gating in a multi-clock domain design where the oscillator feeds a peripheral that sleeps. Housed in a 14-VFQFN exposed pad package measuring 3.20 mm x 2.50 mm with a 0.90 mm profile.","metaTitle":"DSC2044FI2-F0022T MEMS XO – Dual 100 MHz HCSL, ±25 ppm","metaDescription":"DSC2044FI2-F0022T from Microchip Technology: MEMS-based XO (Standard), dual 100 MHz HCSL outputs, ±25 ppm stability, 2.25V–3.6V supply, -40°C to 85°C.","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":"HCSL","Series":"DSC2044","Package":"Tape & Reel (TR)","Function":"Enable/Disable","Base Resonator":"MEMS","Package / Case":"14-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Base Product Number":"DSC2044","Frequency Stability":"±25ppm","Frequency - Output 1":"100MHz","Frequency - Output 2":"100MHz","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"60mA (Typ)","Current - Supply (Disable) (Max)":"23 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3eff32647fb983aa0cb41d84f8133f68.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC2044FI2-F0022T/alternatives.json"},"ai":{"faq":[{"question":"How can I order the DSC2044FI2-F0022T or get a price?","answer":"Submit an RFQ through this page.
