That bandwidth means it can distribute a clean clock edge to four loads without adding jitter that would close the timing margin on a 10+ Gbps serializer or a high-speed ADC. ## Multi-protocol input saves a level-shifter The input accepts CML, CMOS, LVDS, and LVPECL levels. On a mixed-signal board where the clock source might be an LVDS oscillator and the destination is an LVPECL ADC, this buffer handles the translation internally — no external resistor network or AC-coupling cap network needed. ## Industrial temp and small package Operating temperature spans -40°C to 85°C, so it survives outdoor base-station cabinets and factory-floor enclosures without a heater. The 16-LFCSP-WQ (3x3 mm) package fits tight layouts, and the exposed pad pulls heat into the ground plane — make sure the PCB has a thermal via array under the pad.","metaTitle":"ADCLK944BCPZ-R7 Clock Fanout Buffer 1:4 7GHz LFCSP","metaDescription":"Analog Devices ADCLK944BCPZ-R7 SiGe fanout buffer, 1:4 ratio, 7 GHz max frequency, CML/CMOS/LVDS/LVPECL input, LVPECL output, 16-LFCSP 3x3mm, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"SiGe","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Fanout Buffer (Distribution)","Input":"CML, CMOS, LVDS, LVPECL","Output":"ECL, LVPECL","Series":"SiGe","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"16-WFQFN Exposed Pad, CSP","Frequency - Max":"7 GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"2.375V ~ 3.63V","Number of Circuits":"1","Ratio - Input:Output":"1:4","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"16-LFCSP-WQ (3x3)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.19","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.19000","currency":"USD"},{"qty":10,"price":"$9.20700","currency":"USD"},{"qty":25,"price":"$8.77880","currency":"USD"},{"qty":100,"price":"$7.62270","currency":"USD"},{"qty":250,"price":"$7.28008","currency":"USD"},{"qty":500,"price":"$6.63772","currency":"USD"},{"qty":1500,"price":"$5.78124","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADCLK944.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between ADCLK944BCPZ-R7 and ADCLK946BCPZ-REEL7?","answer":"The ADCLK946BCPZ-REEL7 is a 1:6 fanout buffer with a maximum frequency of 4.8 GHz, while the ADCLK944BCPZ-R7 is a 1:4 buffer rated to 7 GHz. If you need more fanout and can accept a lower frequency ceiling, the 946 is a drop-in package-compatible alternative; if you need the full 7 GHz bandwidth, stick with the 944."},{"question":"Can I download the ADCLK944BCPZ-R7 datasheet?","answer":"The datasheet is available from Analog Devices' website. Search for 'ADCLK944' on their document portal — the -R7 suffix indicates tape-and-reel packaging, but the electrical and mechanical data are identical across the ADCLK944BCPZ variants."},{"question":"What input signal types does the ADCLK944BCPZ-R7 accept?","answer":"It accepts CML, CMOS, LVDS, and LVPECL. The output is ECL or LVPECL. This input flexibility means you can drive it from almost any standard clock source without external level shifting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADCLK944BCPZ-R7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADCLK944BCPZ-R7 when reusing this data.
