GENERAL DESCRIPTION This board is designed to allow the user to evaluate the performance of the ADF4213 Dual 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, SMA connector for the reference input, power supplies and RF and IF output. There is also a loop filter for both sides (20kHz bandwidth) and an RF and IF 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.

PC Cable Diagram 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 RF loop component values are for a 2.35GHz output, with 5mA CP current, VCO 190-2350T, 200kHz channel spacing and 20kHz loop band-width. The component values for the IF side are for a 760MHz output, 5mA CP current, VCO190-775T, 200kHz channel spacing and 20kHz loop band-width. 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 supply. The default settings are 3V for the ADF4213 VDD and 5V for the ADF4213 VP and for the VCO supply. 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 onboard. The 19.2 MHz TCXO from Vectron provides the necessary Reference Input. The PLL on the RF side is made up of the ADF4213, passive loop filter (20kHz bandwidth) and the VCO 190-2350 from Vari-L. The PLL on the IF consistes of the ADF4213, passive loop filter (20kHz bandwidth) and the VCO 190-775. The respective outputs are available at RFOUTand IFOUT through standard SMA connectors. 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 ADF4213. –2– REV.PrA 01/00 EVAL-ADF4213EB2 Figure 3.

If the user runs “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 main software screen appears, follow the steps below for initial setup to interface to the part. Click on Choose Device, and the Device window will appear. Choose the ADF4213 and click OK. Click on the value on the front page to bring up a submenu. Change the value of the parameter. Click the OK button. Use this to change the output frequency, PFD Frequency, Reference Input etc. The Evaluation board feaures an A/D converter whcih allows the volatges supplied and current drawn by the part to be displayed on screen. Press the "Update Voltage and Current Supply" readback these values. The settings for this Evaluation Board are saved under options and presets. Select EVAL-ADF4213EB2. To manually configure the settings do the following: Figure 5.
