The 2.16 GHz maximum output frequency targets high-speed serial links: 10GbE, CPRI/OBSAI, JESD204B ADC/DAC reference clocks, and FPGA transceiver reference tiers. The 2:6 input-to-output ratio means you can feed one or two reference sources and get six conditioned clock outputs, each independently programmable in frequency and format. The divider/multiplier block (Yes/Yes) lets you synthesize frequencies that aren't integer multiples of the input — useful when the system needs a 156.25 MHz Ethernet clock from a 10 MHz TCXO. ## Output format flexibility — one part, four logic families Each of the six outputs can be independently set to LVCMOS, LVDS, 2VPECL, or LVPECL levels. That means a single LMK04033BISQX/NOPB can drive a 100 MHz LVCMOS clock to a FPGA fabric, a 312.5 MHz LVPECL clock to a SerDes reference, and a 1.25 GHz LVDS clock to a JESD204B ADC — all from one device. The differential input/output support (Yes/Yes) ensures the high-frequency paths maintain signal integrity over board traces. The supply voltage is tight at 3.15 V to 3.45 V: the 3.3 V rail must be clean and within 5 % regulation; a noisy supply will push the PLL phase noise above the datasheet floor. ## 48-WQFN with exposed pad — thermal and layout notes Housed in a 48-lead WQFN (7x7 mm) with an exposed pad. This part can be designed into new production without worrying about obsolescence-driven respins. The base product number LMK04033 covers a family of clock conditioners; the /NOPB suffix confirms lead-free (RoHS) construction.","metaTitle":"Texas Instruments LMK04033BISQX/NOPB Clock Conditioner, PLL","metaDescription":"Texas Instruments LMK04033BISQX/NOPB clock conditioner with PLL, 2.16 GHz max frequency, 2:6 input:output ratio, LVCMOS/LVDS/LVPECL I/O, -40°C to 85°C, 48-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":"Clock Conditioner","Input":"LVCMOS, LVDS, LVPECL","Output":"LVCMOS, LVDS, 2VPECL, LVPECL","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"2.16GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Divider/Multiplier":"Yes/Yes","Number of Circuits":"1","Base Product Number":"LMK04033","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":"$15.0480","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2739492f39a7ccf814dd60aec1ed6a91.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What output types does LMK04033BISQX/NOPB support?","answer":"Each of the six outputs can be independently configured as LVCMOS, LVDS, 2VPECL, or LVPECL.
