The 2.25V–3.6V supply range lets it run from a common 2.5V or 3.3V rail without an extra regulator. Frequency stability is ±25 ppm across the -20°C to +70°C commercial range — tight enough for 10GbE reference clocks and CPRI line timing where a ±50 ppm oscillator would eat into the link budget. ## Package and layout constraints The 20-VFQFN exposed-pad package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm.","metaTitle":"DSC400-0202Q0109KE2T MEMS XO – LVPECL, 153.6/176.875 MHz","metaDescription":"Microchip DSC400-0202Q0109KE2T: dual-output LVPECL XO (153.6 MHz & 176.875 MHz), ±25 ppm stability, MEMS resonator, 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":"LVPECL","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":"153.6MHz","Frequency - Output 2":"176.875MHz","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dafa7ad99233da79a125bb7188cdbad7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC400-0202Q0109KE2T/alternatives.json"},"ai":{"faq":[{"question":"Is the DSC400-0202Q0109KE2T RoHS compliant?","answer":"The part is listed under the DSC400 series which is RoHS-compliant per Microchip's standard material declaration.
