Abstract: A system for synchronizing a local audio processing clock rate of a digital signal processor (DSP) to an audio clock rate of a network to which the DSP is connected. The system includes an adjustable clock synthesizer that is configured to establish the local audio processing clock rate of the DSP. The DSP is configured to generate events that are associated with the local audio processing clock rate of the DSP. The DSP is further configured to monitor the generated events over time and based on the monitored events cause the adjustable clock synthesizer to adjust the local audio processing clock rate of the DSP to better match the network audio clock rate.

Abstract: Various implementations include a common mode voltage controller for a self-boosting push pull amplifier. In some implementations, input signal are processed by: calculating, based upon the input signal, a maximum duty cycle to achieve a target differential in an output of the self-boosting push pull amplifier; calculating, based on the input signal, a set of control parameters associated with adjusting a common mode voltage of the output; and generating, based on the input signal, a pair of signals configured to adjust the common mode voltage of the output, wherein the pair of signals include a gain adjustment and offset based on the maximum duty cycle and the set of control parameters, and wherein the pair of signals are configured to maintain the target differential in the output of the self-boosting push pull amplifier as the common mode voltage is adjusted to a different operating point.

Abstract: Various implementations include systems for amplifying input signals. In particular implementations, a system includes a common mode voltage controller configured to receive an input signal and output a pair of adjusted signals; a modulator that generates a pair of pulse width modulation (PWM) signals in response to the adjusted signals; and a self-boosting push pull amplifier configured to receive the PWM signals and generate an amplified output, wherein the self-boosting push pull amplifier is configured to generate a differential mode voltage representative of an amplified version of the input signal, wherein the adjusted audio signals generated by the common mode voltage controller include a dynamically adjusted gain and duty cycle offset that causes the self-boosting push pull amplifier to operate with a reduced common mode voltage.

Abstract: A remote node for bi-directional digital audio data and control communications includes remote components including: a remote transceiver; a remote low-voltage power supply that provides power to the other remote node components; and a sub-system that derives a master clock signal from received digital audio data. The sub-system includes a phase-locked loop (PLL) that is locked to a PLL input signal and outputs a remote node clock signal, and a switch that selects the PLL input signal from the derived clock signal and the remote node clock signal. The remote node is enabled to receive over a two-wire communication network digital audio data and digital control signals, and to transmit over the network digital control signals. The remote power supply has an input that is configured to be coupled to the network to derive the power for the remote node from power coupled to the network by a host end.
