PRODUCTION DATA.
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 31. For applications utilizing single-ended 50-Ω coaxial cable, the unused data pin (DOUT–, RIN–) should utilize a 0.047-µF capacitor and should be terminated with a 50-Ω resistor.
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/O’s require a 0.1-µF AC coupling capacitors to the line.
