LVDS output signaling keeps the differential swing tight (350 mV typical into 100 Ω), which reduces radiated EMI compared to single-ended LVCMOS at these frequencies — a practical advantage for dense PCB layouts with multiple clock domains. Operates from 2.25V to 3.6V, so it runs directly off a 2.5V or 3.3V rail without an intermediate LDO — the Enable/Disable function lets the system power down the oscillator when the clock domain is idle. Housed in a 20-VFQFN with exposed pad (5.00mm x 3.20mm, 0.90mm height), the thermal pad must be soldered to a PCB ground plane with thermal vias to dissipate heat — the MEMS resonator itself draws minimal current, but the LVDS output stage benefits from a low-inductance ground return.","metaTitle":"DSC400-3333Q0099KI1T MEMS XO, LVDS, Quad-Output, 20-VFQFN","metaDescription":"Microchip DSC400-3333Q0099KI1T MEMS XO, LVDS output, quad-frequency (148.35/148.5/156.25/208.333333/197.8/198 MHz), 2.25V–3.6V, -40°C–85°C, 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":"LVDS","Series":"DSC400","Package":"Tape & Reel (TR)","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":"148.35MHz, 148.5MHz","Frequency - Output 2":"156.25MHz","Frequency - Output 3":"208.333333MHz","Frequency - Output 4":"197.8MHz, 198MHz","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/528b19bec90af858f699f483a2d753c6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the function of the DSC400-3333Q0099KI1T?","answer":"It is a MEMS-based XO (standard) that generates four independent LVDS output clocks from a single 20-VFQFN package.
