a
Evaluation Board For Fractional-N PLL Frequency Synthesizer
EVAL-ADF4153EB1
GENERAL DESCRIPTION
FEATURES Self-Contained Board including Synthesizer, VCO and Loop Filter (1.7 to 1.8GHz) Designed for 10MHz PFD Spacing & 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 -103dBc/Hz @ 1kHz offset
This board is designed to allow the user to evaluate the performance of the ADF4106 Frequency Synthesizer for PLL's (Phase Locked Loops). The block diagram of the board is shown below. It contains the ADF4153 synthesizer, a pc connector, 10MHz TCXO for the reference input, SMA connectors for the power supplies and RF output. There is also a low pass loop filter (20kHz) and a VCO (Vaari-L VCO190-1750T) on board. The eval board is setup for a 10MHz PFD comparison frequency. 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 Loop Filter Components:
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.
Loop component values shown in the circuit diagram are for 1.75GHz RF output, 2.5mA CP current, VCO1901750T VCO, 10MHz PFD frequency, 20kHz loop bandwidth, phase margin = 45 degrees. N = 175. On the evaluation kit CD is a copy of ADIsimPLL software. This allows the user to create new filter designs and model the frequency and time domain responsees of these loops. It also has a useful report and schematic option.

The board is powered from a single 9V battery. The power supply ciruitry allows the user to choose 3V for the ADF4153 VDD and either 3V or 5V for the ADF4106 VP, and for the VCO supply. The default settings are 3V for the ADF4153 VDD and 5V for the ADF4153 VP and for the VCO supply. It is very important to note that the ADF4153VDD should never exceed the ADF4153 VP. This can damage the device. All components necessary for LO generation are catered for on-board. The 10MHz TCXO from Fox provides the necessary Reference Input. The PLL is made up of the ADF4153, passive loop filter (20kHz) and the VCO1901750T VCO 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. -2-

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/ Analog Devices/ADF_Frac". To run the software, click on ADF_Frac_Rev2.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 ADF4153 and click OK. The Main Interface window will now appear. (See Figure 5) Click on Update All registers. The data is now set up, and other features can now be examined by the user.
To change RF VCO Output Frequency and/or channel spacing, click on the text of the RF VCO Output Frequency. The Output Frequency window will appear. Click on Charge Pump Current Setting and the Current Setting window will appear. Grab the pointer to set the Charge Pump Current Setting. Click OK.
