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

and V

, and for the VCO supply. The

default settings are 3V for the ADF4113 V

and 5V for the

ADF4113 V

and for the VCO supply. It is very important

to note that the ADF4113 V

should never exceed the

ADF4113 V

. This can damage the device.

All components necessary for LO generation are on-
board. The 10 MHz TCXO from Vectron provides the
necessary Reference Input. The PLL is made up of the
ADF4113, passive loop filter (20kHz bandwidth) and the
VCO 190-1750 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 refer-
ence input. In this case, they need to insert SMA connec-
tors 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 1750MHz RF output, 5mA CP current, VCO190-
1750T, 200kHz channel spacing and 20kHz loop band-
width.

Figure 5. Software Front Panel

Software Description

The software comes on a CD marked "ADF4xxx evalua-
tion software". If the user double clicks on "setup.exe" on
the CD, then the install wizard installs the software. Fol-
low the on-screen directions. The software will be in-
stalled in a default directory called
"C:\ProgramFiles\Analog Devices\ADF4XXX_rev0".

The installation will create a shortcut under Analog De-
vices by default. The program can be run by clicking on
ADF4XXX_rev0.
On running the software a panel appears which asks the
user to choose the device to progam. Select the ADF4113.
The front panel will appear with some arbitrary values.

The evaluation board can be setup exactly by clicking
"Eval Board" near the top right corner of the panel. From
the following menu select ADF4113EB2.
This will program the device to the recommended settings
for the setup (i.e. charge pump current, prescaler, polarity
etc.) The user can adjust any of the settings by clicking
with the left mouse button on that feature and adjusting it
accordingly. The drop-down menus contain options to
examine the various test-modes or to set the configuration
options.

There is also a facility to monitor the Supply and Charge
Pump Voltage as well as the Device Current. To get the
most up to date reading just click on the "UpdateVoltage
and Current Display Button".
