| FM/AM tuner IP - industry's first |
|
A few years ago, FM tuners were essentially analog designs. A major transformation has occurred with the advent of integrated circuits and with the introduction of new FM features such as RDS (Radio Data System) providing associated text annotation to the music being currently played. Many of the functions in an FM tuner are now performed digitally. However, existing product offerings still require external SAW filters. In addition, the digital functions of these FM tuners are realized in dedicated digital hardware, and are not able to reconfigure their parameters to optimize their reception in a congested or strongly fading channel. Kaben leverages its SIF techniques to drastically simplify the architecture and remove costly external components. This filter not only achieves excellent (SAW like) filtering performance, it is exceedingly robust to semiconductor process variations, and temperature changes. Further, the filter is programmable in bandwidth and center frequency, enabling adaptive reception to different FM channels. Inclusion of this novel RF filter into an FM tuner significantly reduces the cost of the Bill of Materials. Further, for the first time, it enables an FM tuner to be integrated as a secondary function onto a CMOS die, with the host function being, for example, an MP3 player.
