Accompanying Software allows complete control of syn-
thesizer functions from PC using Windows 95/98/NT.
Battery Operated: Choice of 3V or 5V supplies
On-Board Monitoring of Voltage and Current
Typical RF Phase Noise Performance of -84dBc/Hz @1kHz
offset.
Typical IF Phase Noise Performance of -90dBc/Hz @1kHz
offset.
Typical Spurious Performance of batter than -80dBc
@200kHz offset.

GENERAL DESCRIPTION
This board is designed to allow the user to evaluate
the performance of the ADF4212 Frequency Synthesizer for PLL's (Phase Locked Loops). The block
diagram of the board is shown below. It contains the
footprint for a ADF4212 synthesizer, a pc connector,
SMA connector for the reference input, power supplies and RF output. There is also a loop filter and a
VCO for both the RF and IF section on board. A
cable is included with the board to connect to a pc
printer port.
The package also contains Windows 95/98/NT 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 ADF4212.
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 board is powered from a single 9V battery. The
power supply ciruitry allows the user to choose either 3V
or 5V for the ADF4212 V
supply. The default settings are 3V for the ADF4212 V
and VP, and for the VCO
DD
DD
and 5V for the ADF4212 VP and for the VCO supply. It
is very important to note that the ADF4212 V
never exceed the ADF4212 V
. This can damage the de-

vice.
All components necessary for LO generation are catered
for on-board. The TCXO connector provides the necessary Reference Input. The RF PLL is made up of the
ADF4212, passive loop filter and the VCO 190-1750T
from Vari-L. The output is available at RFOUT through
a standard SMA connector. The IF PLL is made up of the
ADF4212, passive loop filter 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 to as shown on
the silkscreen and block diagram.

Software Description
The software comes on a CD. If the user double clicks on
“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 device window appears, choose ADF4212 and
click OK. The main software panel now appears. Click on
Eval Board in the top right hand side of the main software
screen. The Eval Board Window now appears. Click on
Eval-ADF4212EB1 and Click OK. This will set the correct data for the board configuartion. The device has now
EV AL-ADF4212EB1
been programmed and other features can now be examined by the user.
