It distributes one of three selectable input sources to eleven outputs at frequencies up to 3.1 GHz, making it a single-chip clock-tree solution for high-speed SerDes, FPGA reference clocks, and backplane timing. The 3.1 GHz maximum frequency covers the fundamental clock rates of PCIe Gen4/5, 10G/25G Ethernet, and JESD204B interfaces. At these speeds, the 3:11 fanout ratio eliminates the need for external clock fanout trees — one device drives eleven loads with matched skew. The LMK00301SQX/NOPB is a current-production part, so there is no last-time-buy date to track.","metaTitle":"Texas Instruments LMK00301SQX/NOPB Clock Buffer, 3.1 GHz","metaDescription":"TI LMK00301SQX/NOPB fanout buffer, multiplexer, translator. 3:11 ratio, 3.1 GHz max, CML/HCSL/LVDS/LVPECL input.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","Type":"Fanout Buffer (Distribution), Multiplexer, Translator","Input":"CML, HCSL, HSTL, LVDS, LVPECL, SSTL, Crystal","Output":"HCSL, LVCMOS, LVDS, LVPECL","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"3.1 GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Number of Circuits":"1","Base Product Number":"LMK00301","Ratio - Input:Output":"3:11","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-WQFN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.2265","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a153b98bb208940d183b5059baf841c4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What input and output signal types does LMK00301SQX/NOPB support?","answer":"The outputs can be configured as HCSL, LVCMOS, LVDS, or LVPECL, enabling level translation within the same device."},{"question":"Can LMK00301SQX/NOPB translate LVDS to LVPECL?","answer":"Yes.
