9.2.1 Design Requirements

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 28.

Table 13. Design Parameters

DESIGN PARAMETER EXAMPLE VALUE
VDDIO 1.8 V
AC-Coupling Capacitor for DOUT0± and DOUT1± with 92x deserializers 100 nF
AC-Coupling Capacitor for DOUT0± and DOUT1± with 94x deserializers 33 nF

For applications using single-ended 50-Ω coaxial cable, the unused data pins (DOUT0-, DOUT1-) should use a 15-nF capacitor and should be terminated with a 50-Ω resistor.

DS90UB949-Q1 COAX_AC_COUPLE.gifFigure 29. AC-Coupled Connection (Coaxial)

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.
