The 1:8 ratio means a single oscillator or PLL output can drive eight downstream loads — ADC/DAC clock inputs, SerDes reference clocks, FPGA global clock pins — without needing a separate buffer per load. Both input and output paths are differential (Yes/Yes), which preserves signal integrity across the board and rejects common-mode noise picked up on long traces. ## Supply rail and thermal environment The part runs from a 3.15 V to 3.45 V supply — a tight 3.3 V ±4.5 % rail. No official pin-compatible second source or successor is listed in the family, so the BOM depends on this exact TI part number.","metaTitle":"LMK01020ISQ/NOPB Fanout Buffer, 1.6 GHz, 1:8 LVPECL","metaDescription":"Texas Instruments LMK01020ISQ/NOPB fanout buffer (distribution) and divider.","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), Divider","Input":"Clock","Output":"LVPECL","Series":"-","Package":"Bulk","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"1.6 GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Number of Circuits":"1","Ratio - Input:Output":"1:8","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-WQFN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/416ad37eabff06df091b499dec3ac8e2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum frequency of LMK01020ISQ/NOPB?","answer":"The maximum frequency is 1.6 GHz.
