That frequency ceiling covers the reference clocks for most high-speed ADCs, DACs, and FPGA transceivers up to 12 Gbps line rates. The part integrates a single PLL with a 3:15 input-to-output ratio, meaning you can feed it three reference sources and distribute fifteen cleaned clocks across the board. ## Supply rail tolerance — why 3.3V needs to stay tight The supply range is 3.15 V to 3.45 V — a narrow window that demands a regulated 3.3 V rail with less than 5 % total tolerance including ripple. If your board's 3.3 V bus droops to 3.0 V under load, this part is out of spec. Plan a low-noise LDO or a switching regulator with post-filter for this rail. ## Signal interface flexibility — matching the I/O banks Inputs accept LVCMOS, LVDS, or LVPECL levels, which covers the common oscillator and reference output formats. Outputs can be programmed as HSDS, LCPECL, LVCMOS, LVDS, or LVPECL — that's five format options, so the same part can feed a LVPECL ADC clock input on one bank and an LVDS FPGA reference on another. All I/O pairs are differential-capable, which is the right choice for routing clean clocks across a noisy digital board. It belongs in outdoor telecom base stations, factory-floor Ethernet switches, and instrumentation that lives in an unheated enclosure. Not a commercial 0-70°C part — if your BOM calls for this code, the design already expects the extended range.","metaTitle":"LMK04826BISQ/NOPB Jitter Cleaner PLL, 2.5 GHz Max, 64-WQFN","metaDescription":"TI LMK04826BISQ/NOPB PLLatinum jitter cleaner, 2.5 GHz max output, 3.15-3.45V supply, -40°C to 85°C, 64-WQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","PLL":"Yes","Type":"Jitter Cleaner","Input":"LVCMOS, LVDS, LVPECL","Output":"HSDS, LCPECL, 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":"2.5GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Base Product Number":"LMK04826","Ratio - Input:Output":"3:15","Operating Temperature":"-40°C~85°C","Supplier Device Package":"64-WQFN (9x9)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$24.2000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55bc2e6a1e64b447deafa366fb63204a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum output frequency of the LMK04826BISQ/NOPB?","answer":"The maximum output frequency is 2.5 GHz.
