Output frequencies are 125 MHz, 100 MHz, 200 MHz, and 156.25 MHz — a set that directly serves common Ethernet, PCIe, and SerDes reference clock requirements without extra PLLs or fanout buffers. The MEMS resonator replaces a quartz crystal, giving better resistance to shock and vibration and a faster startup time — useful in networking switches, industrial controllers, and test equipment where a single board may need multiple clock domains. ## Supply voltage and temperature range Supply voltage spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails without an intermediate regulator. The operating temperature range is -20°C to +70°C, which suits commercial and most indoor industrial environments — not rated for extended automotive or outdoor telecom enclosures. Frequency stability is ±25 ppm across the full temperature and supply range, tight enough for most 1 GbE and SATA reference clock jitter budgets. ## Active lifecycle, no obsolescence pressure Product status is Active per the manufacturer — no last-time-buy window, no NRND flag. The Enable/Disable function on the pinout lets the system shut down unused outputs for power savings.","metaTitle":"DSC400-3333Q0104KE2T MEMS XO, LVDS","metaDescription":"Microchip DSC400-3333Q0104KE2T: MEMS XO, LVDS, quad output (125/100/200/156.25 MHz), ±25 ppm stability, -20°C to +70°C, 20-VFQFN, active production.","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":"±25ppm","Frequency - Output 1":"125MHz","Frequency - Output 2":"100MHz","Frequency - Output 3":"200MHz","Frequency - Output 4":"156.25MHz","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/9e9c3232d32a630e5b70b197be3a7eb2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between DSC400-3333Q0104KE2T and DSC400-3333Q0104KE1T?","answer":"The order code suffix differentiates output format and frequency plan.
