It accepts a wide range of differential and single-ended input standards — CML, HCSL, HSTL, LVDS, LVPECL, SSTL, and crystal — and outputs HCSL, LVCMOS, LVDS, or LVPECL. The 3:1 input multiplexer feeds a 1:9 fanout buffer, delivering up to 3.1 GHz on the differential outputs. The part operates from a 3.15 V to 3.45 V supply — a tight 3.3 V rail with 5 % tolerance. Housed in a 40-WFQFN with an exposed thermal pad (6 mm × 6 mm body). Reworking this package needs a preheat profile that brings the board to 150°C before the hot-air nozzle touches the part; the exposed pad is the last joint to wet, so a bottom-side preheater helps avoid cold solder on the ground slug.","metaTitle":"TI LMK00308SQX/NOPB Fanout Buffer, 3.1 GHz, 3:9 Ratio","metaDescription":"Texas Instruments LMK00308SQX/NOPB fanout buffer, multiplexer, translator. 3.1 GHz max frequency, 3:9 input:output, 40-WQFN.","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":"40-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":"LMK00308","Ratio - Input:Output":"3:9","Operating Temperature":"-40°C~85°C","Supplier Device Package":"40-WQFN (6x6)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.9295","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7cdf3cb5cb800f36f9eb913345a70a4b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the input and output types supported by LMK00308SQX/NOPB?","answer":"The LMK00308SQX/NOPB accepts CML, HCSL, HSTL, LVDS, LVPECL, SSTL, and crystal inputs.
