The
Main Controls
tab (see Figure 5) selects the RF and user
configurable register settings. Consult the register descriptions
of the
ADF4355-2
data sheet for details. Default settings are
recommended for most registers.
In the
RF Settings
, ensure that
VCOout(MHz)
equals the
VCO frequency. Set the
Output divider
to give the required
RFoutA± (MHz
).
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 the
CP current
to match the value used
for the loop filter design.
