matching the differential impedance of the bus (taking
into account any reduced impedance due to loading).
Traces, Cables, and Connectors
The characteristics of input and output connections
affect the performance of the MAX9157. Use con-
trolled-impedance traces, cables, and connectors with
matched characteristic impedance.
Ensure that noise couples as common mode by run-
ning the traces of a differential pair close together.
Reduce within-pair skew by matching the electrical
length of the traces of a differential pair. Excessive
skew can result in a degradation of magnetic field can-
cellation. Maintain the distance between traces of a dif-
ferential pair to avoid discontinuities in differential
impedance. Minimize the number of vias to further pre-
vent impedance discontinuities.
Avoid the use of unbalanced cables, such as ribbon
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 the
receiver.
Board Layout
A four-layer PC board that provides separate power,
ground, input, and output signals is recommended.
Keep the LVTTL/LVCMOS and BLVDS signals separat-
ed to prevent coupling.
