FEATURES
General Purpose PLL Evaluation Board excluding Synthe-
sizer, VCO, Loop Filter for generating generic PLL stan-
dards.
Com patible w ith ADF4110 and ADF4116 synthesizer fam i-
lies.
Accom panying Softw are allow s com plete control of syn-
thesizer functions from PC
Battery Operated: Choice of 3V or 5V supplies
T his board is designed to allow the user to evaluate
the performance of the ADF411X Frequency Synthe-
sizer for PLL's (Phase Locked Loops). T he block
diagram of the board is shown below. It contains the
footprint for a ADF411X synthesizer, a pc connector,
SMA connector for the reference input, power sup-
plies and RF output. T here is also a footprint for a
loop filter and a VCO on board. A cable is included
with the board to connect to a pc printer port.
T he package also contains windows software to allow
easy programming of the synthesizer.

voltage is too low to sustain the required 3V or 5V for the
board supply.
Loop component values shown in the circuit diagram are
for 900MHz RF output, 5mA CP current, VCO190-
902T , 200kHz channel spacing and 20kHz loop band-
width.
Figure 1. Evaluation Board Silkscreen
T he board is powered from a single 9V battery. T he
power supply ciruitry allows the user to choose either 3V
or 5V for the ADF4113 VDD and VP, and for the VCO
supply. T he default settings are 3V for the ADF411X VDD
and 5V for the ADF411X VP and for the VCO supply. It
is ver y im por tant to note that the AD F4113 VD D should
never exceed the AD F411X VP . This can dam age the de-
vice.
All components necessary for LO generation are catered
for on-board. T he T CXO connector provides the neces-
sary Reference Input. T he PLL is made up of the
ADF411X, passive loop filter and the VCO 190-XXXT
from Vari-L. T he output is available at RFOUT through
a standard SMA connector. If the user wishes they may
use their own power supplies and reference input. In this
case, they need to insert SMA connectors to as shown on
the silkscreen and block diagram.
T he AD7706 A/D converter is used to monitor the power
supply voltage and current consumption of the ADF411X.
T his helps the user pick the optimum synthesizer settings for
power consumption and also provides an alert if the battery

Click on RF VCO Output Frequency, and the Output
Frequency window will appear. Enter the output frequency
and PFD reference frequency, and click OK.
Click On Prescaler, and the Prescaler window will appear.
Grab the pointer, and choose the desired prescaler value.
C lick OK.
T he software comes on a CD. If the user double clicks on
“setup.exe”, then the install wizard installs the software.
Follow the on-screen directions. T he software will be
installed in a default directory called “C:/Program Files/
AD F4XXX/AD F4XXX_rev0”. T o run the software,
simply double-click on “adf4XXX_rev0.exe”.
Click on Charge Pump Current Setting 2 or Charge
Pump Current Setting 1 and the Current Setting window
will appear. Grab the pointer to set the Charge Pump
Current Setting. Click OK.
Click on the RF PD Polarity button to set the RF PD
Polarity bit.
Before the main software screen appears, the Device win-
dow appears, which will ask the user to choose which de-
vice is being evaluated. Choose the device being evaluated
and click OK.
T he Main Interface window will now appear. (See Figure
5)
Click on Choose Port, and the Port Connector window
will appear. Choose the port that the cable is connected to
on the PC and click OK. (Normally LPT 1)
Click on Reference Frequency, and the Reference Fre-
quency window will appear. Enter the reference frequency
being used and click OK.
T he data is now set up, and other features can now be exam-
ined by the user.
