Applications Information
Power-Supply Bypassing
Bypass each supply pin with high-frequency surface-
mount ceramic 0.1µF and 0.001µF capacitors in paral-
lel as close to the device as possible, with the smaller
valued capacitor the closest to the supply pin.
Differential Traces and Termination
Trace characteristics affect the performance of the
MAX9206/MAX9208. Use controlled-impedance media.
Avoid the use of unbalanced cables such as ribbon or
simple coaxial cable. Balanced cables such as twisted
pair offer superior signal quality and tend to generate
less EMI due to canceling effects. Balanced cables
tend to pick up noise as common mode, which is
rejected by a differential receiver.
Eliminate reflections and ensure that noise couples as
common mode by running differential traces close
together. Reduce skew by matching the electrical
length of the traces. Excessive skew can result in a
degradation of magnetic field cancellation.
Maintain a constant distance between the differential
traces to avoid discontinuities in differential impedance.
Avoid 90° turns and minimize the number of vias to fur-
ther prevent impedance discontinuities.
