= GSM900 Evaluation Board For PLL Frequency Synthesizer EVAL-ADF4113EB1 FEATURES Self-Contained Board including Synthesizer, VCO and Loop Filter for generating GSM frequencies (819MHz to 915MHz) Designed for 20kHz Loop Bandwidth Accompanying Software allows complete control of synthesizer functions from PC Battery Operated: Choice of 3V or 5V supplies Typical Phase Noise Performance of -91dBc/Hz @ 1kHz offset Typical Spurious Performance of better than -90dBc at 200kHz offset from carrier 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 synthesizer, 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.

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 ADF4113 VDD and VP, and for the VCO supply. The default settings are 3V for the ADF4113 VDD and 5V for the ADF4113 VP and for the VCO supply. It is very important to note that the ADF4113 VDD should never exceed the ADF4113 VP. This can damage the device. All components necessary for LO generation are on-board. The 13MHz TCXO from Vectron provides the necessary Reference Input. The PLL is made up of the ADF4113, passive loop filter (20kHz bandwidth) and the VCO 190-902 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 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. –2– REV.PrB 04/00 EVAL-ADF4113EB1 Figure 3.

Evaluation Board Circuit Diagram (Page 2) –4– REV.PrB 04/00 EVAL-ADF4113EB1 Software Description The evaluation board software is contained on a CD-ROM which comes in the package. To load the software the user should click 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/Analog Devices”. To run the software, simply go to the Start Menu and choose Program/ADF4XXX/ ADF4XXX_rev0. This will open the software for the evaluation board. The user will be asked to choose which device is being evaluated. Click on the ADF4113 button. Hit OK. The window shown below will now appear. In this panel, click on the "Eval Board" button. Choose ADF4113EB1 from the list on offer. Hit OK. The synthesizer will now be programmed with the correct settings for a GSM system working at 900MHz. 200kHz PFD frequency is set up, 32/33 prescaler is chosen and charge pump current of 5mA is programmed. If the user wishes to change any of the settings then place the cursor over the desired parameter (RF VCO Output Frequency, for example) and click once. This brings up a screen where it is possible to either type in a new value of output frequency or else increment and decrement by the channel spacing. The software also allows monitoring of the device supply voltage, supply current and the charge pump voltage. Simply hit the "Update Voltage and Current Display" button to get an up-to-date reading.
