It handles frequencies up to 300 MHz. The supply rail is 3.15 V to 3.45 V. The industrial temperature range is -40°C to 85°C. ## Lifecycle and sourcing reality This part is marked Active on the lifecycle record — no NRND or LTB flags. It's an Analog Devices current-production item, so no forced redesign or last-time-buy scramble. The -2 suffix denotes LVDS output; the -1 variant (LTC6957IDD-1#TRPBF) outputs LVPECL instead, which matters if your downstream receiver expects a different logic swing. For production, the #TRPBF suffix is the standard tape-and-reel option.","metaTitle":"LTC6957IDD-2#TRPBF Fanout Buffer (Distribution)","metaDescription":"LTC6957IDD-2#TRPBF is an active 1:2 clock fanout buffer from Analog Devices.

There is no NRND or last-time-buy notice, so it remains suitable for new designs."},{"question":"What are the input and output logic types for LTC6957IDD-2#TRPBF?","answer":"The input accepts CML, CMOS, LVDS, or LVPECL signals. The output is LVDS. Both input and output are fully differential."},{"question":"What is the maximum frequency of LTC6957IDD-2#TRPBF?","answer":"The maximum frequency is 300 MHz. That covers gigabit Ethernet reference clocks, FPGA fabric distribution, and ADC/DAC sampling clocks in most industrial systems."},{"question":"Does LTC6957IDD-2#TRPBF have a direct replacement or equivalent part?","answer":"The closest functional equivalent is the LTC6957IDD-2#PBF — same die and LVDS output, but shipped in a tube instead of tape-and-reel. If you need LVPECL output instead of LVDS, the LTC6957IDD-1#TRPBF is the pin-compatible variant. For an extended temperature range, the LTC6957IMS-2#PBF offers the same LVDS output in an MSOP package with the same 300 MHz limit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC6957IDD-2TRPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC6957IDD-2TRPBF when reusing this data.
