DS90UR903Q Datasheet, PDF (28/34 Pages) Texas Instruments – DS90UR903Q/DS90UR904Q 10 - 43MHz 18 Bit Color FPD-Link II Serializer and Deserializer

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 II signal path as illustrated in Figure 26.

For high-speed FPD-Link II 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
Figure 27 shows a typical connection of the DS90UR903Q
Serializer.
