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 Signal and Board Routing Issues
Improper signal routing causes performance problems
such as crosstalk. The MAX9675 has a typical crosstalk
rejection of -62dB at 6MHz. A bad PCB layout
degrades the crosstalk rejection by 20dB or more. To
achieve the best crosstalk performance:
1) Place ground isolation between long critical sig-
nal PCB trace runs. These traces act as a shield to
potential interfering signals. Crosstalk can be
degraded by parallel traces as well as directly
above and below on adjoining PCB layers.
2) Maintain controlled-impedance traces. Design as
many of the PCB traces as possible to be 75
Ω trans-
mission lines. This lowers the impedance of the
traces, reducing a potential source of crosstalk.
More power is dissipated due to the output buffer
driving 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 MAX9675 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.
Power-Supply Bypassing
The MAX9675 operates from a ±5V supply. For dual-
supply operation, bypass all supply pins to ground with
0.1F capacitors.
