The 8V97003 evaluation board is designed for customers to evaluate the functionality and performance of the
8V97003 RF/Microwave Wideband Synthesizer. On the evaluation board, the 8V97003 device can be
programmed and configured with Timing Commander, a PC-based GUI that generates output frequency from
187.5MHz to 18GHz with a very low phase noise and RMS phase jitter. This user manual details the setup of the
EVB and the programming of the 8V97003 using Timing Commander.

2.2 Required Equipment
Several bench equipment are required for the evaluation of the 8V97003. This section describes the functions of
each required equipment.
2.2.1. Power Supply
The evaluation board uses a single +5V DC supply for its power supply. When running the board, set the bench
power supply at 5V/1A. The +5V terminal is connected to J10, and the Ground terminal is connected to J11.
Multiple LDOs on board are used to generate 3.3V to 8V97003 device.
2.2.2. Signal Generator
A signal generator is necessary to generate the reference clock to the 8V97003 RF/Microwave Synthesizer.
Single-ended reference clock is connected to J6, while J8 can be left unconnected. When differential reference
clock is available, connect them to J6 and J8.
Oscillators such as Oven Controlled Oscillators (OCXO) from Wenzel Associates, Inc. can also be used to
generate reference clock to the 8V97003 RF/Microwave Synthesizer. Some examples of these Wenzel
Oscillators are the VHF ULN OCXO (for frequencies from 15MHz to 160MHz) or MXO-FR OCXO (for
frequencies greater than 200MHz). However, a signal generator is recommended for the flexibility to experiment
with different reference clock frequencies.
2.2.3. Phase Noise Analyzer/Spectrum Analyzer
A phase noise analyzer is necessary to evaluate phase noise performance of the 8V97003 RF/Microwave
Synthesizer. A spectrum analyzer is necessary to evaluate harmonic performance. Both of these equipment
have (output) power measurement capability.
2.2.4. Balun
Balun is optional. A balun is used to convert single-ended output of a signal generator to differential output,
which is used to provide reference clock to the 8V97003 RF/Microwave Synthesizer. Another balun can be used
to combine the differential outputs of the 8V97003 to a single-ended signal for measurement with a phase noise
analyzer/spectrum analyzer.
2.2.5. PC
A PC is required to run IDT Timing Commander GUI.

2.3 Hardware Connection
Follow these procedures to set up the evaluation board:
1. Without connecting the bench power supply to the EVB, turn on the bench power supply to make sure the
output voltage and current clamp are set to +5V/1A respectively. Then turn off the bench power supply.
2. Connect bench power supply to EVB: +5V to J10, GND to J11.
3. Connect Signal Generator’s output to J6 if single-ended reference input clock configuration is desired. If
differential reference input clock configuration is desired, connect Signal Generator’s output to a balun’s
unbalanced port – then connect balun’s balanced ports to J6 and J8.
4. Connect RF outputs to measurement equipment.
5. Terminate unused outputs.
6. Connect micro-USB cable: micro-B end of the cable is connected to J12, A-plug is connected to PC.

2.4 Power-up Procedures
Follow the steps below to power up the evaluation board once the hardware connections shown in 1.3 have
been completed:
1. Turn bench power supply on. Initial current consumption of the whole EVB should be around 500mA
2. Set reference clock input frequency and amplitude on Signal Generator – enable Signal Generator output
3. Program 8V97003 RF/Microwave Synthesizer using IDT’s Timing Commander GUI

7. The 8V97003 is now configured. If the lock detection function is properly configured, Lock Detect LED
should light when the PLL locked status is achieved, and the output frequency displayed in the Desired
REF_OUTA/B box should be available for measurements.

3.2 Making Changes to an Existing Configuration
When changes to an existing configuration is necessary, make sure none of the settings in the affected signal
path is locked as to allow the GUI to make appropriate calculation for optimal settings. A locked setting is
indicated by a white lock symbol in a red box ( ). Follow steps a. through c. from Opening an Existing
Configuration before making changes to the existing configuration.
For example, when changing the input reference frequency, make sure the input doubler enable and the input
reference divider settings are unlocked, as shown in Figure 7.
Figure 7. Input Configuration Settings
Another example is when changing the desired output frequency, make sure the Feedback Divider settings are
unlocked, as shown in Figure 8.
Figure 8. Feedback Divider Settings
A quick way to view all “Locked” settings in an existing configuration is to select “Locked” option in “Bit Sets” tab,
as shown in Figure 9.

5. Click on each functional blocks of the block diagram to enter the desired settings/configuration or to check
automatically calculated settings/configuration. An invalid setting/configuration will result in an Error.
Settings/configurations that are not invalid, but not optimum will result in Warning. Error must be resolved
before proceeding.
6. Once all settings have valid values, click the Connect button (chip symbol) at the upper right corner of the
GUI to set up the communication interface.
7. The connection will be established if a valid 8V97003 is detected, and a green band appears at the upper
right corner of the GUI window.
8. Click Write All to program 8V97003 device.
