Evaluation Board for the 7.5 GHz PLL Frequency Synthesizer
PLEASE SEE THE LAST PAGE FOR AN IMPORTANT
WARNING AND LEGAL TERMS AND CONDITIONS.
Rev. 0 | Page 1 of 8
FEATURES
On-board regulators for 3 V, 5 V, 12 V power supplies
Includes OP27 for active filter applications
Designed for simple hook-up to an external VCO board
GENERAL DESCRIPTION
This board is designed to allow the user to evaluate the
performance of the ADF4007 frequency synthesizer for PLLs
(phase locked loops). The block diagram of the board is shown
in Figure 1. It contains the ADF4007 synthesizer, links for
choosing the divide ratio (8, 16, 32, and 64), an SMA connector
for the reference input, and an RF input and output.

HARDWARE DESCRIPTION
The evaluation board is designed to work with an external
VCO. The layout accommodates loop filter components and
also has an op amp (OP27) for an active filter, if needed. The
silk screen for the evaluation board is shown in Figure 2. The
board schematic is shown in Figure 3 and Figure 4.

The board is powered from a single external 15 V supply. The
power supply circuitry allows the user to choose either 3 V or
5 V for the ADF4007 V
P
. The ADF4007 V
DD
is 3.0 V, and the
OP27 V
CC
is 12 V. It is very important to note that the ADF4007
V
DD
should never exceed 3.3 V or the ADF4007 V
P
, whichever
is less. Doing so can damage the device.
VTUNE is available at an output SMA connector. This should
be connected to an external VCO board. The output of this board
should then be connected back into the EVAL-ADF4007EBZ1 at
RFIN. This is split into two equal power levels with one going to
RFOUT and the other going to the RFIN of the ADF4007 to
close the loop in the PLL. The RFOUT can be fed to a spectrum
analyzer to test the output signal. It should have an amplitude of
6 dB down from the VCO specified output level.
