Evaluation Board for Integer-N PLL Frequency Synthesizer
FEATURES
GENERAL DESCRIPTION
Board designed for hook-up to external VCO board
Contains ADF4108 8 GHz frequency synthesizer IC
Accompanying software allows complete control of
synthesizer functions from a PC
Battery operated
The EVAL-ADF4108EBZ1 is designed to allow the user to
evaluate the performance of the ADF4108 frequency synthesizer
for phase-locked loops (PLLs). The block diagram of the board
is shown in Figure 1. It contains the ADF4108 synthesizer, a PC
connector, SMA connectors for the power supplies, and an RF
output. There is also a passive low-pass loop filter. The board is
designed to be hooked up to an external voltage controlled
oscillator (VCO). A cable is included with the board to connect
it to a PC printer port.
The package also contains Windows® software to allow easy
programming of the synthesizer.

EVALUATION BOARD HARDWARE
HARDWARE DESCRIPTION
POWER SUPPLIES
The evaluation board comes with a cable for connecting it to
the printer port of a PC. The silkscreen and PC cable diagram
are shown in Figure 2 and Figure 3.The board schematics are
shown in Figure 5 and Figure 6.
The board is powered from a single 9 V battery. The power
supply circuit gives 3.3 V to the ADF4108 VDD and allows the
user to choose either 3.3 V or 5 V for the ADF4108 VP. The
default settings are 3.3 V for the ADF4108 VDD and 5 V for the
ADF4108 VP.
The ADF4108 VDD should never exceed the ADF4108 VP because
this can cause damage to the device.
Users can use external power supplies. However, in this case,
they need to insert SMA connectors as shown in the silkscreen
(see Figure 2) and block diagram (see Figure 1).
09145-002
VTUNE is available at the output of the SMA connector, and it
should be connected to an external VCO board. For example,
the HMC506LP4 8 GHz VCO from Hittite can be used. Connect
the output of this board back into the EVAL-ADF4108EBZ1 at
RFIN. This splits into two equal power levels, one going to RFOUT
and the other going to the RFIN of the ADF4108 to close the
loop in the PLL. Feed the RFOUT to a spectrum analyzer to test
the output signal. Do not exceed the ADF4108 RFIN input
sensitivity specification of 0 dBm maximum. If the VCO output
power is greater than 6 dB, redesign the power splitting network
consisting of R8, R9, and R10 to give <0 dBm input power to
RFIN. For example, if using the HMC506LP4 VCO, the output
power is typically 14 dBm, and the power splitting network
must be changed in this instance.

EVALUATION BOARD SOFTWARE
SOFTWARE DESCRIPTION
PROGRAMMABLE SOFTWARE SETTINGS
The control software for EVAL-ADF4108EBZ1 is provided on a
bundled installation CD. To install, use the following steps:
To program the software, complete the following:
1.
2.
Double-click setup.exe. The install wizard installs the
software. Note that administrator access is required on the
PC to install the software.
Follow the on-screen instructions. The software is installed
to a default directory: C:/Program Files/Analog Devices/
ADF_Rev_3_x.exe. To run the software from this directory,
double-click ADF_Rev_3_x.exe. Any previous software
revisions should be uninstalled.
2.
3.
Click RF VCO Output Frequency for the Output
Frequency window to appear.
Enter the desired PFD Frequency, in kHz, and click OK.
Click REF IN Frequency and enter the desired frequency
in MHz.
To modify RF Charge Pump Current Setting 1 or
RF Charge Pump Current Setting 2, click the corresponding
text box and the current setting window will appear. The RF
Prescaler settings can be changed the same way.
At this point, the data is now set up, and the user can modify other
features.
09145-006
Prior to the Main Interface Page, a window appears which
prompts you to select the device to be evaluated. Choose the
ADF4106 and the interface option, and then click OK. The
software used for the ADF4106 and ADF4108 is the same.
The Main Interface Page now appears (see Figure 4).
