  • Patent number: 9621290
    Abstract: An apparatus and method are described for compensating for frequency and phase variations of electronic components by processing packet delay values. In one embodiment, a packet delay determination module determines packet delay values based on time values associated with a first and a second electronic component. A packet delay selection module selects a subset of the packet delay values based on the maximum frequency drift of the first electronic component. A statistical parameter determination module evaluates a first and a second parameter based on portions of the subset of packet delay values. A validation module validates the parameters when each portion the subset of packet delay values includes a minimum of at least two packet delay values. An adjustment module compensates for at least one of a frequency variation and a phase variation of the first electronic component based on the parameters if the parameters are both validated.

  • Patent number: 8670459
    Abstract: An apparatus and method of scheduling timing packets to enhance time distribution includes an improved apparatus in a system in which at least one of time and frequency information is derived based on information distributed in timing packets, at least some of the timing packets being transmitted by or received by the apparatus. The improvement includes a scheduling module that determines a first packet transmission time offset of a first timing packet based on a first predetermined identifier associated with the apparatus, and a second packet transmission time offset of a second timing packet based on the first packet transmission time offset and a timing packet spacing that is independent of the first predetermined identifier. The improvement further includes a transmission module that transmits the first timing packet based on the first packet transmission time offset, and the second timing packet based on the second packet transmission time offset.
