SETTING UP THE DIGITAL INTERFACE
The first software step in setting up the AD9833 to make some
measurements is to set the DIGITAL INTERFACE value. The
EVAL-SDP-CB1Z has two connectors plugs: connectorA and
connectorB. Select the connector you want to use with the
AD9837 evaluation board from the drop-down box.
The SPI Frame Frequency (/SYNC) box and SCLK Frequency
box can also be set in this window. If the SPI interface speed has
not been decided, leave the default values shown in Figure 5.
