With a 1.0 ns propagation delay and integrated output pre-emphasis, it compensates for trace and cable losses on long backplane or cable runs — the pre-emphasis boosts the high-frequency content of the output edge, extending the reachable distance before the eye diagram closes. ## Signal-conditioning and timing budget for high-speed links Each of the four channels independently buffers and reshapes the input signal. The 1.0 ns delay adds to the total link latency — for a 2 Gbps NRZ signal (500 ps unit interval), this delay is two bit periods, so the reDriver must be factored into the system timing budget, especially in source-synchronous or forwarded-clock architectures. The output pre-emphasis is a fixed boost applied to the first transition after a steady-state level — it does not adapt to channel length, so the board designer should set the pre-emphasis level (via the device's control pins, per the datasheet) to match the estimated trace loss at 1 GHz (the Nyquist frequency for 2 Gbps). Input capacitance is 3 pF typical per channel, which loads the upstream driver's output — a driver specified for a 5 pF max load will see margin erosion when all four DS15BR400 inputs are connected in parallel, so the upstream fan-out must be checked. ## Package, supply, and compliance for BOM integration The part is listed as RoHS non-compliant, which means it contains lead (Pb) above the 0.1 % threshold — this is typical for many TI high-speed signal-conditioning parts that use leaded solder in the package to avoid tin whisker risk. The BOM must flag this for any RoHS-exempt or leaded-assembly line; it is not suitable for a pure RoHS-compliant production flow without an exemption.","metaTitle":"TI DS15BR400TVS Buffer ReDriver, 4-Ch, 2 Gbps, 48-TQFP","metaDescription":"Texas Instruments DS15BR400TVS 4-channel LVDS buffer/reDriver. 2 Gbps data rate, 1.0 ns delay, output pre-emphasis.

The DS25BR101 supports a higher data rate (3.125 Gbps vs 2 Gbps) and includes input equalization in addition to output pre-emphasis. The DS15BR400TVS is the right choice when four independent LVDS links need cleaning in one package; the DS25BR101 is better for a single high-speed link that needs both receive-side equalization and transmit-side pre-emphasis."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/DS15BR400TVS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/DS15BR400TVS when reusing this data.
