RECONSTRUCTION FILTER APPLICATIONS
Figure 33 illustrates how to use the ADA4430-1 as a dc-coupled
reconstruction filter with a pass band gain of 2 following the
low power
ADV7190/ADV7191
video encoder. One
ADV7190/
ADV7191
output DAC is shown for illustrative purposes, and
the remaining portions of the
ADV7190/ADV7191
are omitted.
The
ADV7190/ADV7191
is operated in 4× oversampling mode.

The 2.4 kΩ resistor, R
SET
, shown in Figure 33 sets the DAC
output current to its minimum full-scale value of 2.16 mA, and
the 600 Ω load resistor produces a full-scale voltage of 1.296 V
at the ADA4430-1 input.
Figure 34 illustrates another reconstruction filter application,
following the
ADV7174
video encoder. As in Figure 33, one
ADV7174
output DAC is shown for illustrative purposes, and
the remaining portions of the
ADV7174
are omitted.
The 1041 Ω resistor, R
SET
, shown in Figure 34, sets the DAC
output current to its minimum full-scale value of 5 mA, and the
262.5 Ω load resistor produces a full-scale voltage of 1.313 V at
the ADA4430-1 input.
The
ADV7174
can produce a maximum full-scale DAC output
current of approximately 35 mA and is therefore capable of
driving the video cable directly; however, as is shown in Figure 34,
the ADA4430-1 offers a lower, power cable-driving option.
Figure 34 reveals the details of how the ADA4430-1 saves
power when driving video cables with terminations at both
ends. A full-scale level at the DAC output produces 2.626 V at
the ADA4430-1 output, which in turn delivers 17.5 mA into
the cable. In the case shown in Figure 27, the output voltage is
1.313 V, but the current driven into the cable is 35 mA twice
that required when the ADA4430-1 is used. Therefore, the
ADA4430-1 allows the video encoder to be operated at its
minimum full-scale output current, and it efficiently handles
the cable-driving burden.
