It accepts LVCMOS, LVDS, or LVPECL reference inputs and delivers six outputs in LVCMOS, LVDS, 2VPECL, or LVPECL formats — covering the common logic families used in ADC/DAC sampling clocks, FPGA reference clocks, and SerDes frame clocks. The 2:6 input-to-output ratio means two independent reference inputs feed the PLL, and six differential or single-ended outputs are available for fan-out across a board. The differential input and output capability (Yes/Yes) keeps jitter low on long traces or backplane routes. The supply range is 3.15 V to 3.45 V — a tight 300 mV window. This forces a clean 3.3 V rail; a standard 3.3 V LDO with 2% tolerance (e.g., 3.3 V ± 66 mV) stays inside the window, but a 3.3 V rail from a switching regulator with 5% ripple may push the PLL out of spec at the low end. Budget a low-noise LDO for this rail.","metaTitle":"LMK04133SQE/NOPB PLLatinum Clock Generator, 1.08 GHz Max","metaDescription":"Texas Instruments LMK04133SQE/NOPB PLLatinum clock generator, 1.08 GHz max frequency, 2:6 input:output, LVCMOS/LVDS/LVPECL I/O, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","PLL":"Yes","Input":"LVCMOS, LVDS, LVPECL","Output":"LVCMOS, LVDS, 2VPECL, LVPECL","Series":"PLLatinum™","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"1.08GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Base Product Number":"LMK04133","Ratio - Input:Output":"2:6","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-WQFN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.9919","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aec93e0b8f1bb03c48d16d6fe0fc53f3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What input signal types does LMK04133SQE/NOPB support?","answer":"It accepts LVCMOS, LVDS, and LVPECL reference inputs.
