The VSC7108 and VSC7104 are Signal
Conditioners designed to carry broadband
data streams, enabling next generation
backplane designs and extending the life
of existing backplanes. The function of
these devices is simple yet powerful,
creating multiple applications just about anywhere high-
speed signals are present.
The integrated equalization capabilities at both the input and
output effectively absorb the effects of signal loss through
copper interconnect, either printed circuit board traces or
cable. A high degree of signal integrity is maintained
throughout the chip by fully differential signal paths. The
signal path is unregistered and fully asynchronous so that
there are no restrictions on the phase, frequency, or signal
pattern on any input. Each high-speed output is a fully
differential switched current driver with on-die terminations
for maximum signal integrity.
