It integrates a phase-locked loop with programmable dividers and multipliers, making it suitable for jitter cleaning and frequency synthesis in base station, test equipment, and data converter clocking applications. The 1.57 GHz maximum output frequency covers the highest-speed serial interfaces and ADC/DAC sample clocks in telecom and instrumentation. The 2:7 input-to-output ratio allows one reference to fan out to seven conditioned clock domains. Differential inputs and outputs are supported on all paths, which preserves signal integrity over board traces longer than a few centimetres at these frequencies. The part operates from a 3.15 V to 3.45 V supply — a clean 3.3 V rail with less than 5 % ripple.","metaTitle":"LMK04001BISQX/NOPB Clock Conditioner, PLL, 1.57 GHz, 48-WQFN","metaDescription":"Texas Instruments LMK04001BISQX/NOPB PLL-based clock conditioner. 1.57 GHz max frequency, 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, 2VPECL, LVPECL","Series":"-","Package":"Tape & Reel (TR)","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":"LMK04001","Ratio - Input:Output":"2:7","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-WQFN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.8010","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2739492f39a7ccf814dd60aec1ed6a91.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can LMK04001BISQX/NOPB accept LVDS inputs?","answer":"Yes.
