It accepts LVCMOS, LVDS, or LVPECL inputs and delivers the same output types across a 3:15 input-to-output ratio — three inputs feeding up to fifteen clock outputs. The single PLL core runs to 3.08 GHz, making it suitable for cleaning clocks in 10G+ Ethernet, wireless base-station, and instrumentation backplanes where jitter budgets are tight. The 3.08 GHz maximum frequency covers the fundamental clock rates for most high-speed serial links and RF sampling converters. The PLL's jitter-cleaning loop filter attenuates wideband phase noise from the reference source. The 3:15 fan-out lets a single cleaned clock drive multiple converters or FPGAs without external fanout buffers.","metaTitle":"LMK04228NKDT Clocking IC, Jitter Cleaner, 3.08 GHz, 64-WQFN","metaDescription":"TI LMK04228NKDT PLL jitter cleaner, 3.08 GHz max, 3:15 I/O ratio, LVCMOS/LVDS/LVPECL, -40 to 85°C, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","PLL":"Yes","Type":"Jitter Cleaner","Input":"LVCMOS, LVDS, LVPECL","Output":"LVCMOS, LVDS, LVPECL","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"64-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"3.08GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Base Product Number":"LMK04228","Ratio - Input:Output":"3:15","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-WQFN (9x9)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.3400","priceTiers":[{"qty":1,"price":"$12.34000","currency":"USD"},{"qty":10,"price":"$11.34200","currency":"USD"},{"qty":25,"price":"$10.87160","currency":"USD"},{"qty":100,"price":"$9.57890","currency":"USD"},{"qty":250,"price":"$9.10880","currency":"USD"},{"qty":500,"price":"$8.52112","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4bca5c45cbb9017d600692f082b32ffd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK04228NKDT/alternatives.json"},"ai":{"faq":[{"question":"What is the frequency range of LMK04228NKDT?","answer":"The PLL operates up to 3.08 GHz maximum frequency.
