GENERAL DESCRIPTION
This board is designed to allow the user to evaluate the
performance of the ADF4113 Frequency Synthesizer for
PLL's (Phase Locked Loops). The block diagram of the
board is shown below. It contains the ADF4113 synthe-
sizer, a pc connector, SMA connector for the reference
input, power supplies and RF output. There is also a
loop filter (20kHz bandwidth) and a VCO on board. A
cable is included with the board to connect to a pc
printer port.
The package also contains windows software to allow
easy programming of the synthesizer.

Hardware Description
The evaluation board comes with a cable for connecting to
the printer port of a PC. The silk screen and cable diagram for
the evaluation board are shown below. The board schematic is
shown on pages 3 and 4.
The board is powered from a single 9V battery. The power
supply ciruitry allows the user to choose either 3V or 5V for
the ADF4113 V
DD
and V
P
, and for the VCO supply. The
default settings are 3V for the ADF4113 V
DD
and 5V for the
ADF4113 V
P
and for the VCO supply. It is very important
to note that the ADF4113 V
DD
should never exceed the
ADF4113 V
P
. This can damage the device.
All components necessary for LO generation are on-board.
The 13MHz TCXO from Vectron provides the necessary
Reference Input. The PLL is made up of the ADF4113,
passive loop filter (20kHz bandwidth) and the VCO 190-902
from Vari-L. The 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.
The AD7706 A/D converter is used to monitor the power
supply voltage and current consumption of the ADF4113.
This helps the user pick the optimum synthesizer settings for
power consumption and also provides an alert if the battery
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 bandwidth.

Software Description
The evaluation board software is contained on a CD-ROM
which comes in the package. To load the software the user
should click on "setup.exe" , then the install wizard installs
the software. Follow the on-screen directions. The software
will be installed in a default directory called "C:/Program
Files/Analog Devices". To run the software, simply go to the
Start Menu and choose Program/ADF4XXX/
ADF4XXX_rev0. This will open the software for the evalua-
tion board. The user will be asked to choose which device is
being evaluated. Click on the ADF4113 button. Hit OK. The
window shown below will now appear.
In this panel, click on the "Eval Board" button. Choose
ADF4113EB1 from the list on offer. Hit OK. The synthesizer
will now be programmed with the correct settings for a GSM
system working at 900MHz. 200kHz PFD frequency is set
up, 32/33 prescaler is chosen and charge pump current of
5mA is programmed.
If the user wishes to change any of the settings then place the
cursor over the desired parameter (RF VCO Output Fre-
quency, for example) and click once. This brings up a screen
where it is possible to either type in a new value of output
frequency or else increment and decrement by the channel
spacing.
The software also allows monitoring of the device supply
voltage, supply current and the charge pump voltage. Simply
hit the "Update Voltage and Current Display" button to get
an up-to-date reading.
