Audio codecs are used in a wide variety of audio and video applications with a multitude of standards and audio rates. This often creates complex situations to support with the limited clock generation capabilities of the host application. Making sense of it all is the task of the digital filters and clock management features of modern audio codecs. By proper reconfiguration of the digital filters, sample rate conversion and flexible clock frequency choices, it is possible to support audio-video applications with modern audio codecs. This white paper discusses solutions for these applications, that help designers to understanding the trade-off decisions to minimize the costs of their SoCs.
