Evaluation Board for the 7.5 GHz PLL Frequency Synthesizer

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

EVALUATION BOARD CONNECTION DIAGRAM

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
OP27 V
V

is 12 V. It is very important to note that the ADF4007

CC

should never exceed 3.3 V or the ADF4007 VP, whichever

DD

. The ADF4007 VDD is 3.0 V, and the

P

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.

TEST PROCEDURE FOR EVAL-ADF4007EBZ1

EQUIPMENT LIST

• EVAL-ADF4007EBZ1 evaluation board

• +15 V power supply

• Signal generator

• Oscilloscope

• Frequency counter

• Multimeter

• 50 Ω terminator

• Two BNC to SMA cables

TEST PROCEDURE

Step 1: Set Link/Switch Positions

1. Ensure that the link/switch positions are as follows:

• LK1: Position A, Vp is 5 V

• M2: 0 (GND)

DD

DD

DD

)
)
)

• M1: 1 (DV

• N2: 1 (DV

• N1: 1 (DV

2. Connect a 50 Ω terminator to J5.

Step 2: Power Up the Evaluation Board

Turn t h e on switch (SW 1) to the on position. The power LED
should come on.

Step 3: Measure the Following Voltages

• J6: +3.0 V

• J7: +5.0 V

• J8: +12.0 V

Step 4: Check the R Counter

1. Apply a 40 MHz, −5 dBm signal to J1 using one BNC to

SMA cable from the signal generator.

2. Measure the output frequency at J3 using an oscilloscope

or a frequency counter. The output frequency should be
10 MHz.

3. Disconnect the signal generator.

Step 5: Check the N Counter

1. Change M2 to 1 and M1 to 0.

2. Apply a 640 MHz, −4 dBm signal to J1 using one BNC to

SMA cable from the signal generator.

3. Measure the output frequency at J3 using an oscilloscope

or a frequency counter. The output frequency should be
10 MHz.
