The MEMS base resonator shrugs off the shock and vibration that can pull a quartz crystal off frequency — useful if the board lives in a fan-cooled chassis, a portable instrument that gets dropped, or a panel that sees conveyor vibration. The 2.25V~3.6V supply range lets this oscillator run directly from a 2.5V or 3.3V rail without a dedicated LDO — the wide tolerance also covers a 3.3V rail that sags under load, so you don't get clock glitches on a brownout. Outputs are configurable as LVCMOS or LVDS — LVCMOS for general-purpose clock distribution to FPGAs or ASICs, LVDS for longer traces or differential clock trees where common-mode noise rejection matters. ## Package, temperature, and board-fit reality At 0.035\" (0.90mm) height, this oscillator fits under a mezzanine card or inside a 1U rack-mount chassis where component height is budgeted to the millimetre.","metaTitle":"DSC400-3133Q0100KE1 MEMS XO","metaDescription":"Microchip DSC400-3133Q0100KE1 MEMS XO: quad-frequency (148.35/148.5/156.25/25/197.8/198 MHz), LVCMOS/LVDS, 2.25-3.6V, 20-VFQFN, active.","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":"148.35MHz, 148.5MHz","Frequency - Output 2":"156.25MHz","Frequency - Output 3":"25MHz","Frequency - Output 4":"197.8MHz, 198MHz","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/587517d44309ad668938e1e7ab5b9225.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the DSC400-3133Q0100KE1 or check stock?","answer":"The DSC400-3133Q0100KE1 is an active Microchip part.
