* Split 75OHM video termination to match the
board transmission line at the filter side and
the rest at the connector side. A single 75OHM
can be used if the board trace is less than 1”.

6.1.1.2 Passive Filter Configuration
In this configuration, an analog reconstruction filter is used instead of a buffer (see Figure
6-2). This configuration requires the following changes:
• VBG_EXTR_VDAC @ 1.1KΩ + 60.4Ω (default value)
• VDACOUTA_P @ 75Ω (default value)
• VDACOUTB_P @ 75Ω (default value)
• VDACOUTC_P @ 75Ω (default value)
• VDACOUTD_P @ 75Ω (default value)
• Remove the buffer/amplifier and replace it with the reconstruction filter, as shown in
Figure 6-2.
