SCAN15MB200
Dual 1.5 Gbps 2:1/1:2 LVDS Mux/Buffer with
Pre-Emphasis and IEEE 1149.6
General Description
The SCAN15MB200 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 lay-
out, 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.
Integrated IEEE 1149.1 (JTAG) and 1149.6 circuitry supports
testability of both single-ended LVTTL/CMOS and high-
speed differential PCB interconnects. 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.
