GENERAL DESCRIPTION
This board is designed to allow the user to evaluate the performance of the ADF411X Frequency Synthe­sizer 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 sup­plies 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.

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 supply. The default settings are 3V for the ADF411X V
and VP, and for the VCO

and 5V for the ADF411X VP and for the VCO supply. It
is very important to note that the ADF4113 V 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 neces­sary 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

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 win­dow appears, which will ask the user to choose which de­vice 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 Fre­quency 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 exam­ined by the user.
