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.
