2.35GHz Dual Evaluation Board For
PLL Frequency Synthesizer
BLOCK DIAGRAM
REV.PrA 01/00
GENERAL DESCRIPTION
This board is designed to allow the user to evaluate
the performance of the ADF4213 Dual Frequency
Synthesizer for PLL's (Phase Locked Loops). The
block diagram of the board is shown below. It con-
tains the ADF4213 synthesizer, a pc connector, SMA
connector for the reference input, power supplies and
RF and IF output. There is also a loop filter for both
sides (20kHz bandwidth) and an RF and IF 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 ADF4213 V
DD
and V
P
, and for the VCO
supply. The default settings are 3V for the ADF4213 V
DD
and 5V for the ADF4213 V
P
and for the VCO supply. It
is very important to note that the ADF4213 V
DD
should
never exceed the ADF4213 V
P
. This can damage the de-
vice.
All components necessary for LO generation are on-
board. The 19.2 MHz TCXO from Vectron provides the
necessary Reference Input. The PLL on the RF side is
made up of the ADF4213, passive loop filter (20kHz
bandwidth) and the VCO 190-2350 from Vari-L. The
PLL on the IF consistes of the ADF4213, passive loop
filter (20kHz bandwidth) and the VCO 190-775. The
respective outputs are available at RFOUTand IFOUT
through standard SMA connectors. 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 ADF4213.
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.
The RF loop component values are for a 2.35GHz output,
with 5mA CP current, VCO 190-2350T, 200kHz channel
spacing and 20kHz loop band-width.
The component values for the IF side are for a 760MHz
output, 5mA CP current, VCO190-775T, 200kHz chan-
nel spacing and 20kHz loop band-width.

Software Description
The software comes on a CD. If the user runs
"ADF4XXXEvaluationSoftware.exe" on the CD, 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\ADF4xxx Evaluation Software". To run the
software, simply double click on "ADF4XXX Eval
Software.exe".
The front panel of the evaluation board software is shown
below.
When the main software screen appears, follow the steps
below for initial setup to interface to the part.
Click on Choose Device, and the Device window will
appear. Choose the ADF4213 and click OK.
The settings for this Evaluation Board are saved under
options and presets. Select EVAL-ADF4213EB2. To
manually configure the settings do the following:
Click on the value on the front page to bring up a
submenu. Change the value of the parameter. Click the
OK button. Use this to change the output frequency, PFD
Frequency, Reference Input etc.
The Evaluation board feaures an A/D converter whcih
allows the volatges supplied and current drawn by the part
to be displayed on screen. Press the "Update Voltage and
Current Supply" readback these values.
