* 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.
