2) Maintain controlled-impedance traces. Design as
many of the PC board traces as possible to be 75
transmission lines. This lowers the impedance of the
traces, reducing a potential source of crosstalk.
More power dissipates due to the output buffer dri-
ving a lower impedance.
3) Minimize ground current interaction by using a good
ground plane strategy.
In addition to crosstalk, another key issue of concern is
isolation. Isolation is the rejection of undesirable feed-
through from input to output with the output disabled.
The MAX4357 achieves a -110dB isolation at 6MHz by
selecting the pinout configuration such that the inputs
and outputs are on opposite sides of the package.
Coupling through the power supply is a function of the
quality and location of the supply bypassing. Use
appropriate low-impedance components and locate
them as close as possible to the IC. Avoid routing the
inputs near the outputs.
