It is orderable today for both prototype and production quantities.","metaTitle":"DSC400-1111Q0090KE1 MEMS XO – 10/27/148.5/125 MHz, LVCMOS","metaDescription":"Microchip DSC400-1111Q0090KE1 MEMS XO: four LVCMOS outputs at 10, 27, 148.5, 125 MHz. ±50 ppm stability, 2.25–3.6 V supply. 20-VFQFN package.","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","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":"10MHz","Frequency - Output 2":"27MHz","Frequency - Output 3":"148.5MHz","Frequency - Output 4":"125MHz","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/92effcbeab49e36cc7458b2e824c3f24.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC400-1111Q0090KE1 available in tape and reel?","answer":"The listed package option is Tube.
