DS15MB200 Dual 1.
5 Gbps 2:1/1:2 LVDS Mux/Buffer with Pre-Emphasis
General Description
The DS15MB200 is a dual-port 2 to 1 multiplexer and 1 to 2 repeater/buffer.
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 and outputs interface to LVDS or Bus LVDS signals such as those on National’s 10-, 16-, and 18- bit Bus LVDS SerDes, or to CML or LVPECL signals.
