This quad-output architecture replaces up to four single oscillators, saving board space and reducing BOM count in high-speed clock trees for networking, FPGA, and SerDes applications. Supply voltage spans 2.25 V to 3.6 V, allowing direct connection to 2.5 V or 3.3 V rails without an external regulator — simplifies power distribution in mixed-voltage designs. ## Active lifecycle and package details No official successor or second-source is listed; the DSC400 series remains the current offering. Packaged in a 20-VFQFN exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), supplied on tape & reel.","metaTitle":"DSC400-3333Q0016KI1T MEMS XO – LVDS, Quad Output, Active","metaDescription":"Microchip DSC400-3333Q0016KI1T MEMS XO, LVDS output, quad frequencies (25/50/125/150 MHz & 100/156.25 MHz), ±50 ppm stability, -40°C to 85°C, 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":"±50ppm","Frequency - Output 1":"25MHz, 50MHz, 125MHz, 150MHz","Frequency - Output 2":"100MHz, 156.25MHz","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/b1fa89bbb593bb9f15bbf883a84023ea.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to DSC400-3333Q0016KI1T in this Crystals & Oscillators family?","answer":"No pin-compatible alternative is listed in the DSC400 series evidence.
