APPLICATIONS INFORMATION
SNLS322E â JUNE 2010 â REVISED APRIL 2013
AC COUPLING
The SER/DES supports only AC-coupled interconnects through an integrated DC balanced decoding scheme.
External AC coupling capacitors must be placed in series in the FPD-Link III signal path as illustrated in
Figure 38.

Figure 38. AC-Coupled Connection
For high-speed FPD-Link III transmissions, the smallest available package should be used for the AC coupling
capacitor. This will help minimize degradation of signal quality due to package parasitics. The I/Oâs require a 100
nF AC coupling capacitors to the line.
TYPICAL APPLICATION CONNECTION
Figure 39 shows a typical connection of the DS90UB901Q Serializer.

The "Optional" components shown are
provisions to provide higher system noise
immunity and will therefore result in higher
performance.
