GENERAL DESCRIPTION

This board is designed to allow the user to evaluate
the performance of the ADF411X Frequency Synthe-
sizer for PLL's (Phase Locked Loops). The 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. There 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.

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

and V

, and for the VCO

supply. The default settings are 3V for the ADF411X V

and 5V for the ADF411X V

and for the VCO supply. It

is very important to note that the ADF4113 V

should

never exceed the ADF411X V

. This can damage the de-

vice.
All components necessary for LO generation are catered
for on-board. The TCXO connector provides the neces-
sary Reference Input. The PLL is made up of the
ADF411X, passive loop filter and the VCO 190-XXXT
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 ADF411X.
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 band-
width.

Software Description

The 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. The software will be
installed in a default directory called "C:/Program Files/
ADF4XXX/ADF4XXX_rev0". To run the software,
simply double-click on "adf4XXX_rev0.exe".

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.
The 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 LPT1)
Click on Reference Frequency, and the Reference Fre-
quency window will appear. Enter the reference frequency
being used and click OK.

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.
Click OK.
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.
The data is now set up, and other features can now be exam-
ined by the user.
