The 3.2 GHz maximum frequency means it can handle the fastest ADC/DAC reference clocks and FPGA transceiver reference inputs without adding jitter. ## 1:14 fanout and output format flexibility With a 1:14 input-to-output ratio, this single chip replaces a tree of multiple fanout buffers, reducing PCB area and clock tree complexity. Each output can be set to CMOS, LVDS, or LVPECL independently — so a board mixing a CMOS FPGA fabric clock with LVDS ADC clocks and LVPECL DAC clocks can all be fed from the same buffer. The integrated PLL (Yes) allows the device to clean up a noisy reference or generate a multiplied output, though the part is classified as a clock buffer rather than a full clock generator. ## Active production, industrial temperature range The part is ROHS3 compliant and supplied in a 48-LFCSP (7x7) package — a 7 mm square QFN with an exposed pad for thermal management. The tape-and-reel variant suits automated assembly lines. ## Supply voltage and design-in notes A clean 3.3 V rail with low ripple is essential — any noise on the supply couples into the clock outputs and degrades phase noise.","metaTitle":"HMC7043LP7FETR Clock Buffer IC – Analog Devices, 3.2 GHz","metaDescription":"Analog Devices HMC7043LP7FETR clock buffer with PLL, 3.2 GHz max frequency, 1:14 input-to-output ratio, CMOS/LVDS/LVPECL outputs, 48-LFCSP package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"PLL":"Yes","Type":"Clock Buffer","Input":"Clock","Output":"CMOS, LVDS, LVPECL","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"48-VFQFN Exposed Pad, CSP","Frequency - Max":"3.2GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.135V ~ 3.465V","Divider/Multiplier":"Yes/No","Number of Circuits":"1","Ratio - Input:Output":"1:14","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"48-LFCSP (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$31.85","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$31.85000","currency":"USD"},{"qty":10,"price":"$29.37600","currency":"USD"},{"qty":25,"price":"$28.05560","currency":"USD"},{"qty":100,"price":"$25.08520","currency":"USD"},{"qty":250,"price":"$23.92992","currency":"USD"},{"qty":500,"price":"$22.77470","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/61d42eeffb29c5441757aef19ebe4f3e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between the HMC7043LP7FETR and the AD9516-1BCPZ-REEL7?","answer":"Both parts are clock distribution ICs from Analog Devices with PLL, 1:14 input-to-output ratio, and CMOS/LVDS/LVPECL outputs.
