8.2.1 Design Requirements

For the typical design application, use the parameters listed in Table 8-4.

Table 8-4 Design Parameters

DESIGN PARAMETER	EXAMPLE VALUE
VDDIO	1.8 V or 3.3 V
VDD11	1.1 V
VDD18	1.8 V
AC Coupling Capacitor for STP with DS90UB63x CSI-2 Serializer: RIN[3:0]±	33 nF - 100 nF (50V/X7R/0402)
AC Coupling Capacitor for Coaxial with DS90UB63x CSI-2 Serializer: RIN[3:0]+	33 nF - 100 nF (50V/X7R/0402)
AC Coupling Capacitor for Coaxial with DS90UB63x CSI-2 Serializer: RIN[3:0]-	15 nF - 47 nF (50V/X7R/0402)
AC-Coupling Capacitor for STP with DS90UB633A-Q1: RIN[3:0]±	100 nF (50V/X7R/0402)
AC-Coupling Capacitor for Coaxial with DS90UB633A-Q1: RIN[3:0]+	100 nF (50V/X7R/0402)
AC-Coupling Capacitor for Coaxial with DS90UB633A-Q1: RIN[3:0]-	47 nF (50V/X7R/0402)

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 Figure 8-6. For applications using single-ended 50-Ω coaxial cable, terminate the unused data pins (RIN0–, RIN1–, RIN2–, RIN3–) with an AC-coupling capacitor and a 50-Ω resistor.

Figure 8-7 AC-Coupled Connection (Coaxial)

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.
