MAIN CONTROLS
The Main Controls tab (see Figure 4) selects the RF and user
configurable register settings. Consult the register descriptions
of the
ADF4356 data sheet for details. Default settings are
recommended for most registers.
In the
RF Settings
section, ensure that the
VCOout (MHz) box
equals the VCO frequency. Set the Output divider dropdown
menu to give the required RFoutA± (MHz ).
Ensure that the Reference freq. value equals the applied
reference signal. The PFD frequency is calculated from the
reference frequency, the R counter, the reference doubler, and
the reference divide by 2. Ensure that the value in
PFD (MHz)
matches the value specified in the loop filter design.
In the
Register 4 section, program the CP current dropdown
menu to match the value used for the loop filter design.
