Abstract
An oscillator arrangement having an oscillator configured to generate an oscillation signal having two half-cycles, an input configured to receive a synchronization signal including synchronization triggers, a synchronizer configured to reject a synchronization trigger received during a first part of a half-cycle and to synchronize the oscillator to a synchronization trigger received during a second part of the half-cycle, and a controller configured to prolong the second part of the half-cycle in response to receiving a synchronization trigger during the first part of the half-cycle.
Claims20
An oscillator arrangement, comprising:
- an oscillator configured to generate an oscillation signal having two half-cycles;
- an input configured to receive a synchronization signal including synchronization triggers;
- a synchronizer configured to reject a synchronization trigger received during a first part of a half-cycle and to synchronize the oscillator to a synchronization trigger received during a second part of the half-cycle;
- and
- a controller configured to prolong the second part of the half-cycle in response to receiving a synchronization trigger during the first part of the half-cycle.
A method for synchronizing an oscillator, comprising:
- receiving, by an input, a synchronization signal including synchronization triggers;
- rejecting, by a synchronizer, a synchronization trigger received during a first part of a half-cycle of an oscillation signal generated by the oscillator;
- synchronizing, by the synchronizer, the oscillator to a synchronization trigger received during a second part of the half-cycle;
- and
- prolonging, by a controller, the second part of the half-cycle in response to receiving a synchronization trigger during the first part of the half-cycle.
