4 / 24 page Si473x-B20 4 Rev. 0.5 1. Product Overview The Si473x receivers are the industry's first fully-integrated multiband radio receiver ICs from antenna input to audio output. They require minimal external components with no factory alignment. The Si473x receivers reduce the receiver footprint by >90% versus traditional AM/FM solutions. The Si473x also offer best-in-class performance with the most features. The high integration and complete system production test simplifies design-in, increases system quality, and improves manufacturability. The Si473x receivers include advanced seek algorithms, adjustable soft mute, auto-calibrated digital tuning, and FM stereo processing. In addition, the Si473x ICs provide a programmable reference clock and an I2C-compatible 2-wire control interface. The Si4731/35/37/39 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 these features, the Si4731/35/37/39 enables broadcast data such as station identification and song name to be displayed to the end user. 2. Electrical Specifications Table 1.
