It handles up to 3.1 GHz differential signals, making it a fit for high-speed clock distribution in SERDES, base stations, and RF timing chains where signal integrity and low additive jitter matter. ## 3:11 fanout and industrial temperature range Three selectable inputs drive eleven outputs — the 3:1 input mux lets you switch between reference clocks or a local crystal oscillator without an external mux. Supply voltage is 3.15V to 3.45V, a tight window that keeps the internal PLL and output drivers in their linear region.","metaTitle":"LMK00301SQE/NOPB Fanout Buffer, 3.1 GHz, 3:11, 48-WQFN","metaDescription":"Texas Instruments LMK00301SQE/NOPB fanout buffer, multiplexer, translator. 3.1 GHz max frequency, 3:11 ratio, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Fanout Buffer (Distribution), Multiplexer, Translator","Input":"CML, HCSL, HSTL, LVDS, LVPECL, SSTL, Crystal","Output":"HCSL, LVCMOS, LVDS, LVPECL","Series":"-","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Part Status":"Active","Manufacturer":"Texas Instruments","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","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":"$11.9700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a153b98bb208940d183b5059baf841c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK00301SQE%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What input and output signal types does LMK00301SQE/NOPB support?","answer":"It accepts CML, HCSL, HSTL, LVDS, LVPECL, SSTL, or crystal inputs and can output HCSL, LVCMOS, LVDS, or LVPECL.
