8.2.1 Design Requirements
For the typical design application, use the following as input parameters.
| DESIGN PARAMETER | EXAMPLE VALUE |
|---|---|
| VDD33 | 3.3 V |
| VDDIO | 1.8 or 3.3 V |
| VDD12 | 1.2 V |
| AC-coupling capacitor for STP with 925/927: RIN[1:0]± | 100 nF |
| AC-coupling capacitor for STP with 929/947/949: RIN[1:0]± | 33 nF - 100 nF |
| AC-coupling capacitor for Coax with 921: RIN[1:0]+ | 100 nF |
| AC-coupling capacitor for Coax with 921: RIN[1:0]- | 47 nF |
| AC-coupling capacitor for Coax with 929/947/949: RIN[1:0]+ | 33 nF - 100 nF |
| AC-coupling capacitor for Coax with 929/947/949: RIN[1:0]+ | 15 nF - 47 nF |
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 #SNLS4791056. For applications using single-ended 50-Ω coaxial cable, the unused data pins (RIN0– and RIN1–) must use a 15-nF to 47-nF capacitor and must be terminated with a 50-Ω resistor.
Figure 8-4 AC-Coupled Connection (STP)
Figure 8-5 AC-Coupled Connection (Coaxial)For high-speed FPD–Link III transmissions, use the smallest available package for the AC-coupling capacitor. This minimizes degradation of signal quality due to package parasitics.
