The 20-VFQFN exposed pad package (5.00 mm x 3.20 mm, 0.90 mm height) and 2.25 V to 3.6 V supply range let it sit on a mixed-voltage board without a separate regulator — the LVDS outputs swing to the rail, so the common-mode voltage tracks the supply. ## ±25 ppm stability and Enable/Disable function","metaTitle":"DSC400-3333Q0099KE2T MEMS XO – 4-output LVDS Oscillator","metaDescription":"Microchip DSC400-3333Q0099KE2T: MEMS-based XO, LVDS outputs at 148.35/148.5, 156.25, 208.333333, 197.8/198 MHz. ±25 ppm stability, 2.25-3.6 V supply.","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":"148.35MHz, 148.5MHz","Frequency - Output 2":"156.25MHz","Frequency - Output 3":"208.333333MHz","Frequency - Output 4":"197.8MHz, 198MHz","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/528b19bec90af858f699f483a2d753c6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC400-3333Q0099KE2T/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy DSC400-3333Q0099KE2T and how do I get a price?","answer":"This active-production MEMS oscillator is available through independent distribution.
