This replaces up to four discrete quartz oscillators with one device, cutting BOM line count and board area to 5.00 mm × 3.20 mm. Supply voltage spans 2.25 V to 3.6 V, so it runs on a 3.3 V rail or a 2.5 V rail without an external regulator. The 20-VFQFN exposed-pad package requires a thermal via array under the centre pad for heat sinking; the 0.90 mm height fits standard mezzanine card spacing. Frequency stability is ±50 ppm — this holds the clock accuracy across the full temperature range without a TCXO or oven, sufficient for 10/100 Ethernet and most MCU serial interfaces. Product status is Active. New designs can commit without a last-time-buy contingency.","metaTitle":"DSC400-3331Q0097KI1 MEMS XO – 4-Output Clock, LVCMOS/LVDS","metaDescription":"DSC400-3331Q0097KI1 XO (Standard) from Microchip Technology: 16 MHz + 3×50 MHz outputs, LVCMOS/LVDS, -40°C~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":"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":"16MHz","Frequency - Output 2":"50MHz","Frequency - Output 3":"50MHz","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/9af1a0f54c731217ac856ebbe2850382.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC400-3331Q0097KI1 compatible with a 3.3 V supply?","answer":"Yes.
