EVAL-ADF4112EB1 Datasheet, PDF (5/6 Pages) Analog Devices – CDMA Evaluation Board For PLL Frequency Synthesizer

EVAL-ADF4112EB1
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 evalua-
tion board. The user will be asked to choose which device is
being evaluated. Click on the ADF4112 button. Hit OK. The
window shown below will now appear.
In this panel, click on the "Eval Board" button. Choose
ADF4112EB1 from the list on offer. Hit OK. The synthesizer
will now be programmed with the correct settings for a
CDMA system working at 836MHz. 30kHz 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 Fre-
quency, 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.
