External Reference Voltage
If an external reference voltage is used, its circuitry should
receive power from the same plane as the
HMP8190/HMP8191. The external VREF must also be
stable and well decoupled from the power plane. An example
VREF circuit using a band gap reference diode is shown in
Figure 27.
Analog Output Filters
The various video standards specify the frequency response
of the video signal. The HMP8190/HMP8191 uses 2X
oversampling DACs to simplify the reconstruction filter
required. Example post filters are shown in Figure 28. The
analog output filters should be as close as possible to the
HMP8190/HMP8191.
