It runs up to 300 MHz, which covers most ADC/DAC sampling clocks and FPGA reference distribution in the 100–300 MHz band. The supply rail is tight at 3.15V to 3.45V, so the board's 3.3V regulator needs ±4.5% accuracy or better — a standard LDO with 1% tolerance fits.","metaTitle":"LTC6957IDD-2#PBF Fanout Buffer – LVDS Output, 300 MHz","metaDescription":"Analog Devices LTC6957IDD-2#PBF fanout buffer (distribution) with LVDS output, 300 MHz max frequency, industrial temp range -40°C to 85°C.","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":"LVDS","Package":"Tube","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"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a73d42f0fe94cfce038c093f3f032b04.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between LTC6957IDD-2#PBF and LTC6957IDD-1#PBF?","answer":"Both are 1:2 fanout buffers with the same 300 MHz max frequency, supply range, and package. The -2 version outputs LVDS; the -1 version outputs LVPECL. Choose the output logic family that matches your downstream receiver — LVDS for lower swing and lower power, LVPECL for higher noise margin on long traces."},{"question":"Does LTC6957IDD-2#PBF support LVDS output?","answer":"Yes, the -2 suffix indicates LVDS outputs. The input can be CML, CMOS, LVDS, or LVPECL — the buffer translates any of those to LVDS levels."},{"question":"Is LTC6957IDD-2#PBF RoHS compliant?","answer":"Yes, it is ROHS3 Compliant.
