It accepts LVCMOS, LVDS, or LVPECL inputs and delivers 2VPECL or LVPECL outputs, making it suited for cleaning jitter on high-speed serial links where phase noise directly impacts bit-error rate. The integrated divider and multiplier (Yes/Yes) allow frequency synthesis from a reference, while the 2:5 input-to-output ratio provides fanout for distributing a cleaned clock to multiple destinations without external buffers. ## Supply, temperature, and package for board integration Operating from a 3.15 V to 3.45 V supply, the device runs on a single 3.3 V rail common in communications infrastructure. Housed in a 48-WFQFN exposed pad package (supplier device package 48-WQFN 7x7 mm), the thermal pad on the underside must be soldered to a PCB ground plane for adequate heat dissipation. The surface-mount footprint suits automated assembly, but the exposed pad requires a solder stencil aperture that covers at least 50% of the pad area for reliable solder joint formation.","metaTitle":"TI LMK04011BISQE/NOPB Clock Conditioner, 1.57 GHz PLL","metaDescription":"Texas Instruments LMK04011BISQE/NOPB clock conditioner with integrated PLL, 1.57 GHz max frequency, LVCMOS/LVDS/LVPECL inputs, 2VPECL/LVPECL outputs.","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":"2VPECL, LVPECL","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"1.57GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Divider/Multiplier":"Yes/Yes","Number of Circuits":"1","Base Product Number":"LMK04011","Ratio - Input:Output":"2:5","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-WQFN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.2648","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2739492f39a7ccf814dd60aec1ed6a91.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK04011BISQE%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What input and output signal formats does the LMK04011BISQE/NOPB support?","answer":"The clock conditioner accepts LVCMOS, LVDS, or LVPECL inputs and outputs 2VPECL or LVPECL.
