SI4703-D-EVB

RF Evaluation and Development Kits, Boards provide a comprehensive platform for customers to speed up the design and evaluation process of their RF products with ease. SI4703-D-EVB is no exception. It is an evaluation board based on Silicon Laboratories\' SI4703 FM Radio Receiver IC chip and it caters to the needs of the customers who are building and designing consumer-grade products.

Applications of SI4703-D-EVB usually involve consumer applications. An example can be seen in the consumer electronic world, where the SI4703-D-EVB board can be used to make FM radio receivers for cars or even for portable audio electronics. Other applications like the Si4703-D-EVB board can also be seen devices like robots, Wi-Fi enabled objecect recognition systems, mesh-networked products, etc.

The SI4703-D-EVB board has both analog and digital interfaces which is a great advantage in the designing of complex products. The board contains a Silicon Laboratories silicon transistor as the main processor. This works with an antenna to allow the user to search and tune for FM radio stations. Additionally, the dsp processor on the board helps with signal processing and noise management.

The notable features of the SI4703-D-EVB board includes its wide frequency range of 76-108MHz for U.S. application standards. Other features of the board include Temperature Compensation, FM Frequency Recognition, Adjustable Signal Search Sensitivity, Low power consumption of 3-10mA, and a direct connection to a known radio path. The board is designed for optimal work with line-in (from a CD player or iPod, for example) and headphone-out connection. This allows the user to conveniently share sound and design wireless consumer products.

The working principle of SI4703-D-EVB board is quite simple and straightforward. It has an antenna which is connected to the FM receiver chip via an RF input. This antenna can be used to search- and select- the FM radio stations. The signal is amplified in the amplifier IC and sent to the baseband IC where the signal is pre-processed. The pre-processed signal is then sent to the digital processor which demodulates the signal, clean it up and send it over the I/O port. The board has a built in display which is used to show the frequency, signal strength and other parameters.

In summary, SI4703-D-EVB is an evaluation board meant for prototyping of consumer grade products that need RF receiver. It allows easy and fast search and tuning of FM radio station with a wide frequency range that can be adjusted easily. The powerful and efficient processor and interfaces makes SI4703-D-EVB a versatile and cost-effective solution for development and evaluation of RF products.
