DS15MB200 Dual 1.5 Gbps 2:1/1:2 LVDS Mux/Buffer with Pre-Emphasis May 2006 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 overes 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. .. The 3.3V supply, CMOS process, and robust I/O ensure high performance at low power over the entire industrial -40 to +85˚C temperature range.
