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 shown in #SNLS4791057A. For applications using single-ended, 50-Ω coaxial cable, terminate the unused data pins (RIN–) with an AC-coupling capacitor and a 50-Ω resistor.
For high-speed FPD–Link III transmissions, use the smallest available package for the AC-coupling capacitor to help minimize degradation of signal quality due to package parasitics.
