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 pi-
nout 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
www.DataSohreLeVtP4EU.CcLomsignals.
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.
Features
n 1.5 Gbps data rate per channel
n Configurable off/on pre-emphasis drives lossy
backplanes and cables
n LVDS/BLVDS/CML/LVPECL compatible inputs, LVDS
compatible outputs
n Low output skew and jitter
n On-chip 100Ω input and output termination
n 15 kV ESD protection on LVDS inputs/outputs
n Hot plug Protection
n Single 3.3V supply
n Industrial -40 to +85˚C temperature range
n 48-pin LLP Package

Note 6: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, without
exception, to ensure that the system design is reliable over its power supply,
temperature, and output/input loading variables. National does not recom-
mend operation of products outside of recommended operation conditions.
Note 7: VID max < 2.4V
