Digital controller for automatic rate detection and tracking of audio interface clocks |
摘要 |
<p>Systems and methods to achieve a digital audio interface having automatic rate detection and tracking of digital audio streams have been achieved. The system comprises a digital controller working in conjunction with an analog phase-locked loop (PLL). It removes the need to know or communicate in advance the rate at which the interface will be operating, so allowing asynchronous switching between different audio streams. The digital controller acts as a phase-lock loop by modifying the feedback divide ratio of the PLL in order to minimize the phase error between the device clock and an arbitrary audio interface clock.</p> |
