SI4757-A10-AM RF/IF and RFID

RF Receivers

SI4757-A10-AM is a highly integrated advanced analog tuner IC suitable for digital terrestrial radio and HD and other radio signals. It features a high sensitivity and selectivity, low power, fast scanning, and best solid S/N ratio. It integrates advanced signal processing technology, making it suitable for different products and applications. It provides an excellent audio quality and a wide range of radio frequency range from 45MHz to 860MHz.

Application Field

SI4757-A10-AM is mainly used in digital terrestrial radio and digital television (DTV) applications. It is widely used in car radio, home radio, digital radio, E-book, MP3, mobile phones, and other appliances. The SI4757-A10-AM not only can receive FM radio, but also support DAB+ and other radio services. It is easy to use and supports up to three audio/video inputs, which allows the consumers enjoy multiple radio services.

Working Principle

The SI4757-A10-AM works by first scanning through the radio frequency range and searching for the desired signal. Once the signal is detected, the SI4757-A10-AM will then use advanced signal processing technology to convert the signal to an analog audio/video format for processing. The signal is then converted to an FM signal and output through the audio output line. The FM signal is then amplified and sent to a receiver for further processing.

In addition to its radio capability, the SI4757-A10-AM also supports digital television. The signal is compressed to ensure efficient transmission and reception. It is then converted to an NTSC or PAL standard. The signal is then amplified, encoded and sent to the receiver. The receiver then decodes the signal and outputs it in an analog or digital format for further processing.
