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
V_(VDDIO)	1.8 V or 3.3 V
V_(VDD18)	1.8 V
V_(VDD11)( When VDD_SEL = HIGH)	1.1 V
AC-coupling Capacitor for Synchronous Modes, Coaxial Connection: RIN0+ ,RIN1+	33 nF - 100nF (50 WV 0402)
AC-coupling Capacitor for Synchronous Modes, Coaxial Connection: RIN0- ,RIN1-	15 nF - 47nF (50 WV 0402)

AC-coupling Capacitor for Non-Synchronous and DVP Backwards Compatible Modes, Coaxial Connection: RIN0-, RIN1-	47 nF (50 WV 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 V³Link signal path as shown in Figure 8-6 and Figure 8-7. When connected to the TSER953 serializer operating with 10-Mbps back channel, the higher value AC-coupling capacitors are recommended to reduce low frequency attenuation. For applications using single-ended 50-Ω coaxial cable, terminate the unused data pins (RIN0–, RIN1–) with an AC-coupling capacitor and a 50-Ω resistor.

For high-speed V³Link transmissions, use the smallest available package for the AC-coupling capacitor to help minimize degradation of signal quality due to package parasitics.
