Abstract: 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.

Abstract: 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.

Abstract: An oscillator circuit with a voltage controlled oscillator (VCO) comprises a range changing circuit that adapts the d.c. control voltage of the circuit to a control signal suitable for adjusting the VCO to the full frequency range. The voltage level for the control signal can be outside the voltage range delimited by the supply voltages for the circuit. In order to obtain a voltage supply of a sufficient voltage level the output signal of the VCO is used as the input of an a.c. to d.c. converter that provides the necessary higher supply voltage for the range changing circuit.
