Its single PLL with integrated VCO targets high-speed data converter clocking, FPGA reference clocks, and RF LO generation where phase noise floor matters. ## Signal format flexibility Both inputs and outputs support LVCMOS, LVDS, and LVPECL levels, so the part interfaces directly with most ADC/DAC clock inputs, FPGA clock-capable pins, and RF synthesizer reference ports without external level translation. The 2:7 input-to-output ratio provides seven synthesised outputs from one of two selectable reference inputs. ## Supply and thermal design-in The operating temperature range is -45°C to 85°C.","metaTitle":"LMK04208NKDR PLLatinum™ Clock Jitter Cleaner, 1.536 GHz","metaDescription":"TI LMK04208NKDR PLLatinum™ clock conditioner with 1.536 GHz max frequency, LVCMOS/LVDS/LVPECL I/O, -45°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, LVPECL","Series":"PLLatinum™","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"64-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"1.536GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Base Product Number":"LMK04208","Ratio - Input:Output":"2:7","Operating Temperature":"-45°C~85°C","Supplier Device Package":"64-WQFN (9x9)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.5665","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c92b7fc5d078e68a79bd6b4760bcb249.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum output frequency of LMK04208NKDR?","answer":"The maximum frequency is 1.536 GHz, making it suitable for clocking high-speed ADCs (e.g., 1 GSPS-class) and generating RF LO signals in the L-band."},{"question":"Does LMK04208NKDR require external loop filter components?","answer":"Yes, like most PLL-based clock conditioners, the LMK04208NKDR requires an external loop filter — typically a passive RC network connected to the charge pump output.
