No PLL on board, so the output frequency is a divided version of the input, not a synthesized one. The part handles input clocks up to 1.296 GHz, which puts it in the range for high-speed ADC/DAC reference clocks, FPGA transceiver reference clocks, and backplane timing distribution. ## 1:8 fan-out and differential signalling The 1:8 input-to-output ratio means one reference clock feeds eight loads, saving a separate fan-out buffer. Both input and output are differential, so the part keeps common-mode noise rejection through the path. The divider is a Yes on the spec — you can divide the input frequency down — but there is no multiplier, so the output frequency will always be at or below the input frequency. ## Supply and temperature envelope Runs from a 3.15 V to 3.45 V supply rail — that is a tight tolerance, so the board regulator needs to be within 3.3 V ±4.5 %. 48-WFQFN with exposed pad, 7x7 mm body. The thermal pad underneath needs a soldered via array to the ground plane — without it the part derates above 70°C ambient. Surface-mount only; not a field-swap candidate without a hot-air station.","metaTitle":"LMK03000DISQX/NOPB Clock Conditioner, 1.296 GHz, LVDS/LVPECL","metaDescription":"Texas Instruments LMK03000DISQX/NOPB clock conditioner, 1.296 GHz max, 1:8 fan-out, LVCMOS/LVDS/LVPECL inputs, LVDS/LVPECL outputs, -40 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":"No","Type":"Clock Conditioner","Input":"LVCMOS, LVDS, LVPECL","Output":"LVDS, LVPECL","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Package / Case":"48-WFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"1.296GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Base Product Number":"LMK03000","Ratio - Input:Output":"1:8","Operating Temperature":"-40°C~85°C","Supplier Device Package":"48-WQFN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.4110","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What are the exact specifications of LMK03000DISQX/NOPB?","answer":"Clock conditioner, no PLL, 1.296 GHz max input, 1:8 fan-out, LVCMOS/LVDS/LVPECL input, LVDS/LVPECL output, 3.15 V to 3.45 V supply, -40°C to 85°C, 48-WQFN exposed pad."},{"question":"What is the maximum frequency of LMK03000DISQX/NOPB?","answer":"1.296 GHz on the input.
