The DS25MB100 is a signal conditioning 2:1 multiplexer and
1:2 fan-out buffer designed for use in backplane redundancy
or cable driving applications. Signal conditioning features include
input equalization and programmable output Pre-emphasis
that enable data communication in FR4 backplane up
to 2.5 Gbps. Each input stage has a fixed equalizer to reduce
ISI distortion from board traces. All output drivers have four
selectable levels of Pre-emphasis to compensate for transmission
losses from long FR4 backplane or cable attenuation
reducing deterministic jitter. The Pre-emphasis levels can be
independently controlled for the line-side and switch-side
drivers. The internal loopback paths from switch-side input to
switch-side output enable at-speed system testing. All receiver
inputs are internally terminated with 100Ω differential terminating
resistors. All driver outputs are internally terminated
with 50Ω to VCC.
