SI4767-A50-AM

RF Receivers

The SI4767-A50-AM is a cost-effective and highly integrated system-on-chip solution for RF reception applications. Based on the proven RF front-end architecture of the Silicon Labs\' Si47xx family, this ultra-low power receiver integrates an advanced tuner, demodulator, digital signal decoders, and integrated power amplifier for matching to the antenna input.

As a cost-effective, low power consumption receiving solution, the application field of SI4767-A50-AM receiver covers multiple types, including consumer audio hardware, automotive infotainment, communication systems, and other various types of embedded systems.

Working Principle

The SI4767-A50-AM receiver is composed of three main elements: antenna input, RF front-end, and digital audio output. The antenna input comprises a low-noise, wideband matching network, which is matched to the antenna, and connected to the receiver\'s RF front-end. The RF front-end is composed of two main elements: the digital tuner and the demodulator.

The digital tuner is responsible for selecting the desired frequency, which can be adjusted by the system micro-processor or remote control. The demodulator then further processes the selected signal to provide a digital output. This output is then sent to the integrated digital audio output, which is capable of providing a linear and distortion-free audio signal.

In conclusion, the SI4767-A50-AM receiver is a powerful, low-power solution for receiving signals in multiple application fields. Its RF front-end architecture is both rugged and efficient, while its integrated digital audio output provides clean and distortion-free audio for a wide variety of applications.
