    摘要: Various embodiments provide a Phase Interpolator (PI) that receives input clocks, and outputs intersymbol interference-equalized, phase-shifted output clocks. In one embodiment, the Phase Interpolator comprises two PI Conditioners and a PI Mixer. In one embodiment, a PI Conditioner receives input clocks and is controlled by a different phase-shifted input clock by using a suitable circuit element, such as a flip-flop. Collectively, the input clock-controlled PI Conditioner and Mixer act in concert to control the band limiting effect of the PI Conditioner which, in turn, equalizes intersymbol interference.

    摘要: A data reception apparatus obtains an integrated number of bits by integrating the numbers of bits of a bit string, obtains an integrated number of samples by integrating the number of samples obtained by oversampling each bit, obtains an approximated line that indicates correspondence between the integrated number of bits and the integrated number of samples, determines, based on the approximated line, a bit length of a bit string corresponding to a segment in which identical values continue in oversampling data after the integrated number of samples. Even when a receive-side clock source has a degree of clock frequency error against a transmit-side clock source, how many samples one bit of the bit string corresponds to is obtained with an accuracy higher than a period of oversampling (inverse of the number of samples).

    摘要: An information processing apparatus is provided which includes a transmission unit for transmitting a query request for querying another device for a count value held by such other device, a reception unit for receiving a return of the count value from such other device, a correction unit for performing, at a predetermined period, correction processing for synchronizing sampling frequency with such other device based on the received count value, and a reproduction unit for reproducing content in synchronization with such other device based on the sampling frequency. The correction unit corrects by taking into account a Round Trip Time between the transmission of the query request and the reception of the return and residual difference occurred at a previous correction time.

    摘要: Apparatus and methods for quadrature clock signal generation are provided. In certain implementations, an apparatus includes an invertible sine shaping filter configured to receive an in-phase clock signal, a quadrature-phase clock signal, and an inversion control signal. The invertible sine-shaping filter is further configured to filter the in-phase and quadrature-phase clock signals to generate sinusoidal in-phase and quadrature-phase clock signals. The invertible sine-shaping filter is further configured to selectively invert one or both of the in-phase and quadrature-phase clock signals based on an inversion control signal. The apparatus further includes a phase interpolator configured to generate an interpolated clock signal based on a weighted sum of the selectively inverted sinusoidal in-phase clock signal and the quadrature-phase sinusoidal clock signal. The in-phase clock signal and the quadrature-phase clock signal have a quadrature-phase relationship.
