8V97003 EVB User Manual
Evaluation Board
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.

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. -

Page 11: Performance Evaluation With The 8V97003 Evb
The 8V97003 devices provides two differential outputs of CML type. The outputs are “open collector outputs” and can be matched in different ways. By default, a simple resistive matching is used on the 8V97003 EVB. This resistive matching consists of a 50Ω resistor to VDD, with a series AC coupling capacitor. This matching scheme gives the output amplitude a “broadband”... -

(if applicable), loss across frequencies due to transmission line on the EVB must also be characterized. To assist customer with the measurement of trace loss on 8V97003 EVB, a test “coupon” is included in the same PCB manufacturing panel with the main EVB. This test “coupon” consists of the exact copy of the transmission lines on the board and the SMA connectors. -

Page 28: Appendix B - Input Reference Phase Noise Performance
Phase noise measurement results shown in Figure 22, Figure 24, and Figure 25 were obtained with the input reference clock from a bench signal generator. Because the in-band phase noise performance of 8V97003 RF/Microwave Synthesizer is dictated by the phase noise performance of the input reference, the input reference’s phase noise performance is provided in Figure 26. - Page 29 Renesas' products are provided only subject to Renesas' Terms and Conditions of Sale or other applicable terms agreed to in writing.
