National Semiconductor Corp.'s two latest interface products are a pair of 2Gbps signal-conditioning buffer-repeaters that are said to provide the lowest jitter transfer, highest ESD protection of 15kV, and on-chip termination.

The DS15BR400 and DS15BR401 four-channel LVDS buffer-repeaters provide all the features necessary for designing mainstream LVDS multicards or multiboxes. The devices operate from zero to 2Gbps and feature 14ps of total jitter at 1.5Gbps data rates.

With 15kV of ESD protection, the DS15BR400 and DS15BR401 ensure maximum protection for FPGAs, ASICs and other onboard components.

The DS15BR400 and DS15BR401 include configurable pre-emphasis and are well-suited for delivering clean LVDS signals across cables and backplanes found in a wide variety of electronic systems, including telecom, datacom, industrial, medical, automotive and office imaging applications.

Offered in both 32-pin LLP and 48-pin TQFP packages, the DS15BR400 drives up to four LVDS clock and/or data channels over common backplanes or cable configurations. The wide differential input range easily interfaces to LVDS, low voltage positive emitter-coupled logic (LVPECL), or current-mode logic (CML) input levels and the output levels are fully LVDS compliant.

Configurable output pre-emphasis allows the designer to overdrive the outputs. In power-sensitive applications, the power-down per channel mode is useful in minimizing power consumption when all four channels of a single device are not active.

The DS15BR400 has input and output terminations integrated to save board space and maximize signal conditioning. The DS15BR401 has the same features and packaging options as the DS15BR400, but it does not include the integrated receiver termination, which allows it to be used as a multi-drop receiver.

Available now, the DS15BR400 and DS15BR401 cost $3.95 each in quantities of 1,000.
