GENERAL DESCRIPTION
This board is designed to allow the user to evaluate the
performance of the ADF4213 Frequency Synthesizer for
PLL's (Phase Locked Loops). The block diagram of the
board is shown below. It contains the ADF4213 synthesizer, a pc connector, TCXO reference input, power
supplies and IF/RF outputs. Both output channels have a
20kHz loop filter. The IF channel has a 540MHz VCO
while the RF channel has a 900MHz VCO. 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.

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.
RF 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.
IF loop component values are for 540MHz IF output, 5mA
CP current, VCO190-540T, 200kHz channel spacing and
20kHz loop bandwidth.
Figure 1. Evaluation Board Silkscreen
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 VDD and VP, and for the VCO supplies. The
default settings are 3V for the ADF4213 VDD and 5V for the
ADF4213 VP and for the VCO supplies. It is very important
to note that the ADF4213 VDD should never exceed the
ADF4213 VP. This can damage the device.
All components necessary for LO generation are on-board.
The 13MHz TCXO from Vectron provides the necessary
Reference Input. There are two channels controlled by the
ADF4213.
The RF PLL is made up of one half of the ADF4213, a passive loop filter (20kHz bandwidth) and the VCO 190-902T
from Vari-L. The output is available at RFOUT through a
standard SMA connector.
The IF PLL is made up of one half of the ADF4213, a passive loop filter (20kHz bandwidth) and the VCO 190-540T
from Vari-L. The output is available at IFOUT 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 as shown on the silkscreen and block diagram.

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_rev2. This will open the software for the evaluation board. The user will be asked to choose which device is
being evaluated. Click on the ADF4213 button. Hit OK. The
window shown below will now appear.
In this panel, click on the "Eval Board" button. Choose
ADF4213EB1 from the list on offer. Hit OK. The synthesizer
will now be programmed with the correct settings for a GSM
system working at 900MHz RF and 540MHz IF. 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 Frequency, 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.
