ug-435 evaluation board user guide rev. 0 | page 4 of 20 evaluation board har dware t he eval - ADF4351eb1z schematic s are shown in figure 22 to figure 24. power supplies the eval - ADF4351eb1z can be powered either from the usb port or via dc power connectors (4 mm banana connectors). when feeding via banana connectors, 3.75 v to 5.5 v is a suitable feeding voltage. the power supply circuitry allows the user to use one or two separate ldos to feed the ADF4351 (using fewer ldos increases the risk of spur contaminated dc feeds). consult the board schematic in figure 22, figure 23 , and figure 24 to determine a suitable setting. an led, d6, indicates when usb power is available, and anoth er led, d5, indicates when the ADF4351 is powered. s witch s1 is used to power the ADF4351 from the external dc connectors usb port and switch s2 to power from the usb port. in case the usb processor or clock causes spurs on the rf output signal, the user may f eed the evaluation board via the dc connectors and unplug the usb cable, thereby removing power from the usb interface circuitry. there is also a grounded frame surrounding the usb interface circuitry to allow mounting of a shielding box. i nput s ignals the 25 mhz tcxo from rakon provides the necess ary reference signal. an external refin may be used if desired. in this case, disable the on - board tcxo by removing l10 and r59 . r 9 can be populated with 50 to adjust impedance matching of the evaluation boar d to the external reference source. loop filter the loop filter schematic is included in the board schematic on figure 22 . the loop filter component placements are cla rified in figure 2 . figure 2 . loop filter placement figure 3. eval uation board silkscreen o utput s ignals the eval - ADF4351eb1z has two sma output connectors ( differential output s ). the device is quite sensitive to impedance unbalance. if only one port of a differential pair is used, terminate the other with a 50 load. the board contains 7.5 nh shunt inductors on the rf output stages, which is optimum for a frequency range of 1 ghz to 4.4 ghz. lower frequencies than this require larger output stage inductors, or a 50 resistor to v dd , which provides lower output power , but wider frequency bandwidth than the inductors. consult the ADF4351 data sheet for more information. the muxout signal can be monitored at the test point labeled muxout . 10844-002 10844-003
evaluation board user guide ug-435 rev. 0 | page 5 of 20 evaluation board setup procedure s oftware i nstallation the control software and usb drivers for eval - ADF4351eb1z are on the cd, which accompanies the board. if the user runs adf435 x _setup.msi , then the install wizard guides the user through the install process. simply follow the on - screen instructions. the software and usb drivers will be installed i n the default directory called c: \ prog ram files \ analog devices \ adf435 x . the software requires microsofts .net framework version 3.5 or later to be installed on your machine. the installer will automatically download the framework from the microsoft website if you do not have this installed. if you do not have an internet connection or a slow conne ction on the pc, then you can install the .net framework directly from the cd. do this by double - clicking dotnetfx35.exe . once installed, run the adf435 x _setup.msi again. note that to install the dotnetfx35.exe , you need to have windows installer 3.1 or la ter installed. 1. install the analog devices adf435x pll software by double - clicking adf435x _setup.msi . if you are using windows xp, follow the instructions in the windo ws xp software installation guide section (see figure 4 to figure 8 ). if you are using windows vista or windows 7, follow the instructions in the windows vista/7 software installation guide section (see figure 9 to figure 13). not e that the software requires microsoft windows installer and microsoft .net framework 3.5 (or higher). the installer connects to the internet and downloads microsoft .net framework automatically. alternatively, before running adf435x _setup.msi , both the in staller and .net framework can be installed from the cd provided. 2. connect your sdp board (black) or usb adapter board (green) by usb. if you are using an sdp board, the drivers install automatically, and you are ready to run the software. if you are using an usb adapter board on windows xp, follow the steps in the windows xp driver installation guide section (see figure 14 to figure 17). on windows vista or windows 7, the drivers install automatically. windo ws xp software installation guide iure windows xp d software installation setu wiard 1. click next . figure 5. windows xp adf435x software installation, select installation folder 2. choose an installation directory and click next . 10844-004 10844-005
