EV-ADF4356SD1Z

Evaluation and Demonstration Boards and Kits

The EV-ADF4356SD1Z is a Zynq-based radio frequency hardware for Dual Synthesizer Tuning Module by Analog Devices, Inc. This evaluation board and kit is a complete solution for a wireless communication link application using frequency-hopping spread spectrum (FHSS) or direct-sequence spread spectrum (DSSS). The ADF4356 is a highly integrated dual frequency synthesizer IC with a unique architecture that provides excellent phase noise and fast switching speed. The ADF4356 is provided with an on-chip VCO, 2.4GHz and 5GHz RF output, and can operate in frequency ranges from 1.5GHz to 6GHz. The RF output can be tuned to any frequency within the range with a resolution down to 12.5 KHz. The ADF4356 also provides selectable power outputs at voltage levels of 3V, 5V or 7.5V.

The EV-ADF4356SD1Z is designed for use as an RF prototype platform or as an evaluation board for the ADF4356. It provides easy access to the JTAG, security, and power connectors. The board includes an FM_STB to ensure proper operation in noisy environments. An antenna connector for the 2.4 GHz band and a coaxial connector for the 5 GHz band are also included for connecting the RF signals to the external environment. The EV-ADF4356SD1Z is intended to support the development and evaluating of complete wireless communication link. The board is compatible with many software development tools and test and measurement instruments.

EV-ADF4356SD1Z Application Field and Working Principle

The EV-ADF4356SD1Z is suitable for wireless communication link applications such as industrial or commercial radio networks, Wi-Fi and cellular base stations, and medical equipment. It is also ideal for radio frequency applications that require fast switching of frequencies including base stations, frequency hopping applications, and point-to-point radio links. The ADF4356 Evaluation Board and Kit can be used to evaluate the dual frequency synthesizer IC, as well as to evaluate the complete design of the RF communication link.

EV-ADF4356SD1Z includes two integrated circuits (ICs): the ADF4356 RF synthesizer and the FM_STB 24GHz low-noise block downconverter. When the ADF4356 is powered up, the RC oscillator is used to provide a reference signal which is divided and supplied to the frequency dividers in both channels. The frequency dividers use resistor and capacitor networks to set the reference frequency. This reference frequency is compared with the frequency of a reference voltage applied to each channel and the error signal is used to figure the frequency of the two output signals. The FM_STB 24GHz low-noise block downconverter receives the RF output signal from the ADF4356 and converts it to a digital signal that can be processed or transmitted to other systems. The EV-ADF4356SD1Z also provides a secure digital protocol interface and a JTAG interface for programming.

Conclusion

The EV-ADF4356SD1Z Evaluation Board and Kit is a comprehensive solution for wireless communication link applications. It provides an easy interface for the programming and evaluation of the ADF4356 RF synthesizer and the FM_STB 24GHz low-noise block downconverter. The board is designed for applications that require fast frequency switching and provides an RF output with selectable voltage levels and precise frequency resolution.
