Output frequencies cover 148.35 MHz, 148.5 MHz, 156.25 MHz, 208.333333 MHz, 197.8 MHz, and 198 MHz — a spread that suits video clocking (148.5 MHz for 3G-SDI), Ethernet reference (156.25 MHz for 10GbE), and FPGA transceiver cores (208.333333 MHz). ## MEMS reliability vs quartz startup ## Supply and output gating Supply range is 2.25 V to 3.6 V — the part runs on a 2.5 V or 3.3 V rail without a separate regulator. The enable/disable pin gates the LVDS outputs while keeping the PLL alive, so the downstream FPGA can halt its transceiver clocks without re-locking the oscillator. Status is Active per Microchip's current lifecycle.","metaTitle":"DSC400-3333Q0099KI1 MEMS XO – Quad LVDS Output","metaDescription":"Microchip DSC400-3333Q0099KI1: quad-output LVDS XO, MEMS resonator, 148.35/148.5/156.25/208.333333/197.8/198 MHz, ±50 ppm, -40 to 85°C, enable/disable.","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":"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":"208.333333MHz","Frequency - Output 4":"197.8MHz, 198MHz","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/528b19bec90af858f699f483a2d753c6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order DSC400-3333Q0099KI1 or request a quote?","answer":"The part is Active and available through our independent distribution channel.
