This means one clock source can drive two downstream loads without degrading edge rates or adding jitter — a common need in ADC clock trees, FPGA reference distribution, and backplane timing. ## Supply rail and temperature grade for industrial environments Operates from a 3.15V to 3.45V supply — a tight tolerance that suits a regulated 3.3V rail with ±5% margin. ## Package and mounting for high-speed layout The 0.50 mm pitch demands careful fan-out — a 2-layer board is tight; a 4-layer stack-up with ground plane under the pad is recommended for signal integrity. ## Active lifecycle and sourcing posture The Tape & Reel variant (2,500 pieces per reel) is feeder-ready for volume assembly; Cut Tape is also available for prototype builds.","metaTitle":"LTC6957IDD-1#TRPBF Analog Devices Clock Fanout Buffer","metaDescription":"LTC6957IDD-1#TRPBF: Fanout Buffer (Distribution) by Analog Devices. 300 MHz max, LVPECL output, accepts CML/CMOS/LVDS/LVPECL input.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Fanout Buffer (Distribution)","Input":"CML, CMOS, LVDS, LVPECL","Output":"LVPECL","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"12-WFDFN Exposed Pad","Frequency - Max":"300 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 3.45V","Number of Circuits":"1","Ratio - Input:Output":"1:2","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"12-DFN (3x3)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.82","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.82000","currency":"USD"},{"qty":10,"price":"$9.77200","currency":"USD"},{"qty":25,"price":"$9.31720","currency":"USD"},{"qty":100,"price":"$8.09010","currency":"USD"},{"qty":250,"price":"$7.72648","currency":"USD"},{"qty":500,"price":"$7.04476","currency":"USD"},{"qty":1000,"price":"$6.13575","currency":"USD"},{"qty":2500,"price":"$5.90850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a73d42f0fe94cfce038c093f3f032b04.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What input logic does LTC6957IDD-1 accept?","answer":"It accepts CML, CMOS, LVDS, and LVPECL input signals.
