A system includes a first device comprising a first clock generating circuit and a transmitter circuit, and a plurality of second devices, each comprising a respective receiver circuit and a respective second clock generating circuit. The first clock generating circuit may be configured to generate a first clock signal, which may provide internal clocking for the first device. The transmitter circuit may be configured to generate a synchronization signal in response to the first clock signal and wirelessly transmit a broadcast signal communicating only the synchronization signal. The respective receiver circuit may be configured to receive the broadcast signal and present a recovered synchronization signal to the respective second clock generating circuit. The respective second clock generating circuit may be configured to generate a respective intermediate clock signal, synchronize the respective intermediate clock signal with the recovered synchronization signal, and generate a respective second clock signal that provides internal clocking for the second device.

Wirelessly synchronized clock networks

An apparatus includes a first independently clocked device and one or more second independently clocked devices. The first independently clocked device may comprise a clock generator. The clock generator may be configured to generate a clock signal. The first independently clocked device may be configured to wirelessly broadcast a synchronization signal based on the clock signal. The one or more second independently clocked devices may each comprise respective clock generators. The one or more second independently clocked devices may (a) be configured to receive the synchronization signal from the first independently clocked device and (b) synchronize the respective clock generators to the clock signal of the first independently clocked device in response to the synchronization signal.
