20090141842 - Clock signal transmission method in radio communication apparatus, and radio communication apparatus: A radio communication apparatus includes a transmission clock signal generation part, when a harmonic component of a first clock signal used by a clock signal using part agrees with a reception frequency of the radio communication apparatus, generating a second clock signal different from the first clock signal; a clock... Agent: Staas & Halsey LLP

20090141843 - Method and apparatus for determining a skew: The invention provides a method and an apparatus for determining a skew of each data bit of an encoded data word received by a receiver via an interface from a transmitter comprising the steps of performing an error check and correction of the received and sampled encoded data word to... Agent: Coats & Bennett/qimonda

20090141844 - Methods and apparatus for interface buffer management and clock compensation in data transfers: A circuit for data stream buffer management, lane alignment, and clock compensation of data transfers across a clock boundary using a single first in first out (FIFO) buffer in each serial channel is described. The RapidIO® data channel, for example, operates using a clock recovered from the data stream. The... Agent: Ip Legal Services

20090141845 - Digital phase-locked loop operating based on fractional input and output phases: In one aspect, a digital PLL (DPLL) operates based on fractional portions of input and output phases. The DPLL accumulates at least one input signal to obtain an input phase. The DPLL determines a fractional portion of an output phase based on a phase difference between an oscillator signal from...
