That replaces up to six discrete oscillators on a mixed-frequency board — a single BOM line for the entire clock tree. Supply voltage spans 2.25 V to 3.6 V, so it runs directly off a 2.5 V or 3.3 V rail without an intermediate LDO. The Enable/Disable function lets firmware gate the outputs during low-power sleep states. ## Frequency stability and temperature range Rated ±50 ppm frequency stability over -20°C to +70°C — within tolerance for most Ethernet, FPGA, and processor reference clocks. The MEMS resonator is less sensitive to vibration and aging than a quartz crystal, so the long-term drift stays tighter over the product life. Housed in a 20-VFQFN with exposed pad, 5.00 mm x 3.20 mm body, 0.90 mm height.","metaTitle":"DSC400-1111Q0001KE1 MEMS XO – 6 Outputs, LVCMOS, Active","metaDescription":"Microchip DSC400-1111Q0001KE1 MEMS XO: 6 outputs (25/50/125/150/100/156.25 MHz), LVCMOS, 2.25–3.6V supply, ±50 ppm stability, 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","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":"25MHz, 50MHz, 125MHz, 150MHz","Frequency - Output 2":"100MHz, 156.25MHz","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/b1fa89bbb593bb9f15bbf883a84023ea.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the output frequencies of DSC400-1111Q0001KE1?","answer":"The device outputs six LVCMOS frequencies: 25 MHz, 50 MHz, 125 MHz, 150 MHz, 100 MHz, and 156.25 MHz."},{"question":"Is DSC400-1111Q0001KE1 compatible with a 2.5V supply?","answer":"Yes.
