Product description
The Si4735-C40-GU is the first digital CMOS AM/FM radio receiver IC that integrates the complete tuner function from antenna input to audio output. With this IC you can make your own radio.
The Si4735 is a feature-rich solution including advanced seek algorithms, soft mute, auto-calibrated digital tuning, and FM stereo processing. In addition, the Si4735 provides analog or digital audio output and a programmable reference clock. The device supports I2C compatible 2-wire control interface, SPI, and a Si4700/01 backwards-compatible 3-wire control interface.
The Si4735 also incorporates a digital processor for the European Radio Data System (RDS) and the North American Radio Broadcast Data System (RBDS), including all required symbol decoding, block synchronization, error detection, and error correction functions. Using RDS, the Si4735 enables broadcast data such as station identification and song name to be displayed by the user.
Features:
Worldwide FM band support (64-108 MHz)
Worldwide AM band support (520-1710 kHz)
SW band support (2.3-26.1 MHz)
LW band support (153-279 kHz)
Digital FM stereo decoder
RDS/RBDS processor
