This replaces three separate oscillators on the board, saving layout area and reducing BOM line count. Frequency stability is rated at ±25 ppm across the full -40 to +85°C industrial temperature range, which keeps the clock edge jitter within the margin for 1 GbE, PCIe Gen 2, or SATA reference clocks without an external PLL cleanup. The part operates from a 2.25 V to 3.6 V supply rail, covering 2.5 V and 3.3 V logic families without an additional regulator. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the package requires a thermal pad on the PCB for heat sinking. The 0.50 mm pitch QFN demands a 4-layer board for fan-out of the 20 pads; two-layer designs will struggle to route all signals without vias. Microchip lists the DSC400-3333Q0094KI2 as Active.","metaTitle":"DSC400-3333Q0094KI2 MEMS XO – Quad LVDS Output, ±25 ppm","metaDescription":"Microchip DSC400-3333Q0094KI2 MEMS XO: 125/100/100/50 MHz LVDS outputs, ±25 ppm stability, -40 to +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":"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":"±25ppm","Frequency - Output 1":"125MHz","Frequency - Output 2":"100MHz","Frequency - Output 3":"100MHz","Frequency - Output 4":"50MHz","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/35b2def026a15fae95dd8ba842a991e4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC400-3333Q0094KI2 datasheet available?","answer":"The datasheet for the DSC400 series is published by Microchip Technology.
