Optimize FM transmission using digital PLLs

More and more mobile devices such as MP3 players, PDAs, cellphones, personal media players and portable game consoles are carrying audio content. People have explored different ways—with or without wire—to transmit these audio signals to different external equipment, either to listen with a headset or share the content with others. Compared with other technologies, FM transmission provides an attractive alternative with a good balance of convenience, audio quality, power consumption and cost, as it has a huge receiver installation base and the technology is simple and proven.

In this technical article, Jack Kao of KT Micro Inc. discusses more about optimizing FM transmission using digital PLLs.
