Outputs are selectable between LVCMOS and LVDS levels, letting you drive both single-ended logic and differential pairs from the same device without a translator. ## Supply rails and temperature range for your BOM Operating from 2.25 V to 3.6 V, it spans the common 2.5 V and 3.3 V logic rails without an extra regulator — check your rail tolerance; the wide range covers most FPGA and SoC banks. Housed in a 20-VFQFN with exposed pad, measuring 5.00 mm x 3.20 mm and 0.90 mm tall — the thermal pad needs a via array under it for proper soldering and heat sinking.","metaTitle":"DSC400-1133Q0079KE1 XO (Standard) MEMS Oscillator –","metaDescription":"DSC400-1133Q0079KE1: Active XO, quad-output 100/100/66.666/25 MHz, LVCMOS/LVDS, 2.25-3.6V, 20-VFQFN.","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":"100MHz","Frequency - Output 2":"100MHz","Frequency - Output 3":"66.666MHz","Frequency - Output 4":"25MHz","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6c5c0d0689349a7f21a6b84194918c49.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC400-1133Q0079KE1 compatible with a 3.3 V supply?","answer":"Yes, 3.3 V is within the 2.25 V–3.6 V range, so no level shifting is needed."},{"question":"What is the footprint of the DSC400-1133Q0079KE1?","answer":"The 20-VFQFN package measures 5.00 mm x 3.20 mm with a 0.90 mm height.
