Abstract
Embodiments of systems and methods for clock synchronization for transmission of audio information are disclosed herein. In one example, a System on Chip (SoC) includes a Universal Serial Bus (USB) transceiver, an oscillator circuit free of a crystal, a frequency divider, and a clock synchronization calibrator. The USB transceiver is configured to extract a first synchronization clock associated with data received by the USB transceiver. The oscillator circuit free of a crystal is configured to generate an original clock. The frequency divider is configured to generate a second synchronization clock based on the original clock. The clock synchronization calibrator configured to generate a first set of frequency control data based on a frequency difference between the first synchronization clock and the second synchronization clock.
