  • On-chip 100 Ω output termination, optional 100 Ω input termination
  • 15 kV ESD protection on LVDS inputs and outputs
  • Single 3.3V supply
  • Industrial -40 to +85°C temperature range
  • Space saving LLP-32 or TQFP-48 packages
  • Description

    The DS15BR400/DS15BR401 are four channel LVDS buffer/repeaters capable of datarates of up to 2 Gbps. High speed data paths and flow-through pinout minimize internal device jitter and simplify board layout, while pre-emphasis overcomes ISI jitter effects from lossy backplanes and cables. The differential inputs interface to LVDS, and Bus LVDS signals such as those on National's 10-, 16-, and 18- bit Bus LVDS SerDes, as well as CML and LVPECL. The differential inputs and outputs of the DS15BR400 are internally terminated with 100Ω resistors to improve performance and minimize board space. The DS15BR401 does not have input termination resistors. The repeater function is especially useful for boosting signals for longer distance transmission over lossy cables and backplanes.

    The DS15BR400/DS15BR401 are powered from a single 3.3V supply and consume 578 mW (typ). They operate over the full -40°C to +85°C industrial temperature range and are available in space saving LLP-32 and TQFP-48 packages.

    Description:

    DS15BR400 is a four channel LVDS Buffer/Repeater, featuring pre-emphasis with maximum pre-emphasis gain of approximately 6 dB at 750 MHz. The device has internal 100-ohm resistors on both, the inputs and outputs, to improve performance and minimize board size. It utilizes LVDS technology for low power, high-speed and superior noise immunity.




    National Semiconductor follows the provisions of the Product Stewardship Guide for Customers (CSP-9-111C1) and Banned Substances and Materials of Interest Specification (CSP-9-111S2) for regulatory environmental compliance. Details may be found at: www.national.com/en/packaging/greennopb.html. Lead free products are RoHS compliant.

    Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
