The Main Controls tab (see Figure 5) selects the RF and user
configurable register settings. Consult the register descriptions
in the ADF5355 data sheet for details. Default settings are rec-
ommended for most registers.
In RF Settings, ensure that VCOout (MHz) equals the VCO
frequency. Set Output divider to give the required
RFoutA± (MHz).
EV-ADF5355SD1Z User Guide
Ensure that Reference freq 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 Register 4, program CP current to match the value used for
the loop filter design.
