PLL Frequency Synthesizer Evaluation Board
PLEASE SEE THE LAST PAGE FOR AN IMPORTANT
WARNING AND LEGAL TERMS AND CONDITIONS. Rev. 0 | Page 1 of 12
FEATURES
General-purpose PLL evaluation board (the synthesizer, VCO,
and loop filter for generating generic PLL standards are
not included in the evaluation board package)
Compatible with
ADF4110, ADF4111
ADF4116, ADF4117
ADF4107
Accompanying software allows complete control of
synthesizer functions from a PC
Battery operated: choice of 3 V or 5 V supplies
Rogers material substrate for improved RF performance
GENERAL DESCRIPTION
The EVAL-ADF411xEBZ1 evaluation board is designed to evaluate
the performance of the ADF4110, ADF4111, ADF4116, ADF4117,
and ADF4107 frequency synthesizers for phase-locked loops
(PLLs). Figure 1 is the functional block diagram of the board
and shows the frequency synthesizer, a PC connector, and an
SMA connector for the reference input, the power supplies, and
an RF output. There are also footprints for a loop filter and a
voltage controlled oscillator (VCO) incorporated on the board. A
cable is included in the evaluation board package to connect the
evaluation board to a PC printer port.
The evaluation board package contains Windows® based software
to allow easy programming of the frequency synthesizer.

EVALUATION BOARD HARDWARE
HARDWARE DESCRIPTION
The evaluation board package includes a cable for connecting the
EVAL-ADF411xEBZ1 to the printer port of a PC. The silkscreen
and cable diagram for the evaluation board are shown in Figure 2
and Figure 3. The test setup configuration is shown in Figure 4.
The board schematics are shown in Figure 7 and Figure 8.
09146-002
Figure 2. Evaluation Board Silkscreen
The evaluation board is powered from a single 9 V battery. The
power supply circuitry allows the user to individually choose
either 3 V or 5 V for the VDD of the frequency synthesizer, the
VPof the frequency synthesizer, and the supply of the VCO. The
default settings are 3 V for the VDD of the frequency synthesizer
and 5 V for the VPof the frequency synthesizer and for the
supply of the VCO.
It is important to note that the VDD of the frequency synthesizer
should never exceed the VPof the frequency synthesizer because
damage to the device may result.
All components necessary for LO generation are catered for on
board. A temperature compensated crystal oscillator (TCXO)
connector provides the necessary reference input. The PLL
comprises the frequency synthesizer, the passive loop filter, and
the VCO. The output is available at RFOUT through a standard
SMA connector. A different reference input and different power
supplies than those included with the evaluation board package
can be used, if desired. In this case, insert SMA connectors as
shown in the silkscreen (Figure 2) and the cable diagram (Figure 3).

LOOP DESIGN
The evaluation board package does not include a VCO, loop
filter, or frequency synthesizer. The frequency synthesizer and
VCO are chosen by the user, depending on the frequency and
application requirements. The filter can then be designed based
on these requirements by using the ADIsimPLL software. This
software, which is provided on the CD-ROM included in the
evaluation board package, allows the user to enter the loop
parameters. The software then designs the filter and shows the
frequency and time domain analysis of the filter response. The
software also offers useful schematic and report options.
