A first clock (e.g., a data clock) is set for a first sampling cycle to a first phase position within a given unit interval... Agent: Ryan, Mason & Lewis, LLP

20070025485 - Metric sampling method and system: An arbitrary metric stream is processed initially at an interim sampling rate to derive a plurality of samples. The samples are analyzed preferably to determine an estimate of the effective bandwidth of the metric stream. As a result of the analysis, an improved sampling rate is determined and adopted for...

20070025486 - Control message management in physical layer repeater: A repeater is configured to selectively generate and transmit control message packets between wireless stations on both a transmit side and a receive side of the repeater. The repeater manages and manipulates an end to end protocol of the control message packets in a manner that does not change media... Agent: Posz Law Group, PLC

20070025487 - Clock transferring apparatus, and testing apparatus: There is provided a clock transferring apparatus for synchronizing a pattern signal synchronized with a reference clock with a variable clock based on an oscillation source different from that of the reference clock, having a rate clock generating section for generating a rate clock whose number of pulses within a... Agent: Osha Liang L.L.P.

20070025488 - Ram-dac for transmit preemphasis: Described are transmitters with RAM-DAC based pre-emphasis filters that can be updated adaptively without interfering with data transmission. The memory within the RAM-DAC is divided into active and inactive memory locations, in which active memory locations are those to be accessed in the near future, and consequently cannot be updated...
