Software Description
The ADF7010 software comes on an installation CD. Hit
the start button and choose run. Select D:\setup.exe - This
will run the Installshield setup utility. Choose the direc-
tory you wish to install into and proceed.
Once the program is setup run ADF7010.exe to run the
program. The window shown below should appear - you
will need a screen resolution of 1024 x 768 to use the pro-
gram.
You should start by setting up the output frequency. Click
the '915.3MHz' to bring you to the PLL sub-menu.Type
in the output frequency, desired PFD frequency (default
19.2MHz), and the crystal frequency (default =
19.2MHz) used and hit the 'calculate' button. The
prescaler can be chosen by clicking the '4/5'. The blue
toggle buttons allow the user to change between two set-
tings. The green and red toggle buttons turn a feature on
or off.

The charge pump current and power down should be set
next. To move to the charge pump current sub-menu click
on the '2.02mA' setting in blue. Within the charge pump
menu you can choose to set the Rset resistor and the
charge pump current. The default value for Rset on your
eval board is 4.7k. This is an external resistor and will
change the available charge pump settings. You will have
to adjust the loop filter for any changes to the charge
pump current setting, as this will change the stability of
the filter. You can use ADIsimPLL to model these effects.
Click on the drop-down box to select the modulation. To
see the part in PLL mode you should select ASK. This
will allow the user to evaluate phase noise, reference spurs
and output power levels available. The initial offset in the
crystal will cause the absolute output frequency to be off.
This error can be calibrated out using the fractional-N
registers.
