DS90UB903Q Datasheet, PDF (34/41 Pages) Texas Instruments – 10 - 43MHz 18 Bit Color FPD-Link III Serializer and Deserializer with Bidirectional Control Channel

Applications Information
AC COUPLING
The SER/DES supports only AC-coupled interconnects
through an integrated DC balanced decoding scheme. Exter-
nal AC coupling capacitors must be placed in series in the
FPD-Link III signal path as illustrated in Figure 34.

For high-speed FPD-Link III transmissions, the smallest avail-
able 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 100 nF AC coupling
capacitors to the line.
TYPICAL APPLICATION CONNECTION
