Embodiments of systems and methods for transmission of audio information are disclosed herein. In one example, a System on Chip (SoC) includes a wired transceiver module, a wireless module, a Frequency Modulation (FM) demodulation module, and an audio information codec module operatively coupled to the wired transceiver and the FM demodulation module. The wired transceiver module is configured to receive a data packet corresponding to first audio information. The wireless module is configured to receive an FM signal, corresponding to second audio information. The FM demodulation module is configured to output the second audio information based on demodulating the FM signal. The audio information codec module is configured to decode the first audio information and the second audio information based on the data packet and the demodulated FM signal, respectively.

Systems and methods for transmission of audio information

Embodiments of oscillator circuits for wireless transmission of data are disclosed herein. In one example, an oscillator circuit includes an active network and a passive differential network coupled to the active network is disclosed. The active network is configured to generate an active signal for sustaining oscillation of the oscillator circuit. The passive network includes a first subnetwork, a second subnetwork, a first inductor and a second inductor. The first subnetwork is configured to adjust a central value of a resonant frequency of the oscillation. The passive network further includes a second subnetwork configured to further adjust the resonant frequency of the oscillation.

Systems and methods for frequency-modulation

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.
