Applications Information
AC COUPLING
The SER/DES supports only AC-coupled interconnects
through an integrated DC balanced decoding scheme. Exter-
For high-speed Channel Link III transmissions, the smallest
available package should be used for the AC coupling ca-
pacitor. This will help minimize degradation of signal quality
due to package parasitics. The I/O’s require a 0.1 μF AC cou-
pling capacitors to the line.

nal AC coupling capacitors must be placed in series in the
Channel Link III signal path as illustrated in Figure 34.
