frequencies, but in a very large system, there may be
many R-Cs cascaded in series. The cumulative effect is
a slight rolling off of the high frequencies, causing a
“
softening
”
of the picture. There are two solutions to
achieve higher performance. One way is to design the
PC board traces associated with the outputs such that
they exhibit some inductance. By routing the traces in a
repeating
“
S
”
configuration, the traces that are nearest
each other will exhibit a mutual inductance increasing
the total inductance. This series inductance causes the
amplitude response to increase or peak at higher fre-
quencies, offsetting the rolloff from the parasitic capaci-
tance. Another solution is to add a small-value inductor
to the output.
Crosstalk and Board Routing Issues
Improper signal routing causes performance problems.
The MAX4357 has a typical crosstalk rejection of
-62dB at 6MHz. A bad PC board layout degrades the
crosstalk rejection by 20dB or more. To achieve the
best crosstalk performance:
1) Place ground isolation between long critical signal
PC board trace runs. These traces act as a shield to
potential interfering signals. Crosstalk can be
degraded from parallel traces, as well as directly
above and below on adjoining PC board layers.
