| Single PCB for All Broadcast Audio Designs Footprint Compatible The Si47xx family requires only two external components and offers many footprint compatible multi-band receivers. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Highest Level of Integration The Si47xx products are the first fully integrated broadcast audio ICs. These solutions require only two external components and 15 mm2 or less of board space in contrast to dozens of external components and as much as five times the amount of board space for competing products. The high level of integration, small footprint and low power consumption enable the integration of multi-band receivers, FM receivers, FM transmitters, FM transceivers, or data receivers into any consumer device such as mobile phones, MP3 accessories, media players, and navigation devices. Best-in-Class Performance The Si47xx family's excellent selectivity and sensitivity improve user experience and result in reduced interference and increased reception. Its advanced digital audio processing delivers optimum sound quality superior to other solutions even in the presence of variable signal conditions, and its digital architecture enables performance that is unmatched compared to standard analog solutions. With advanced AM and FM seek algorithms and software programmable audio flexibility, the Si47xx family provides an unmatched level of performance. Easiest to Design and Manufacture The Si47xx family is delivered as a fully tested system requiring no factory alignment. Its simple hardware design reduces development time, unlike other solutions that require dozens of components limiting production flow and adding performance variability across products. Evaluation and design is easy with a full reference board including schematics and layout files and a robust development graphical user interface (GUI). These solutions also accept a wide range of antenna inputs from headphone cables to ultra-small ferrites and integrated tuned loops. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| RDS and RBDS Support The Si47xx family includes a series of solutions that incorporates a digital processor for the European Radio Data System (RDS) and the US Radio Broadcast Data System (RBDS) including all required symbol decoding, block synchronization, error detection, and correction functions. Using this feature, these products enable data such as station identification, artist name, and song title to be transmitted to and displayed on any RDS/RBDS receiver. The Si4749/06 incorporate a high-performance RDS/RBDS decoder based on patented methodologies, and deliver excellent RDS/RBDS sensitivity performance, synchronization to RDS/RBDS at high BLER levels and RDS/RBDS data decoding with superior decoder reliability, making them ideal for performance-intensive Traffic Message Channel (TMC) applications in navigation devices.
