    Abstract: The present invention provides a spread spectrum clock generation system, comprising a digitally controlled Phase Locked Loop (PLL), and a Digital Frequency Profile Generator to create a near optimal frequency modulation profile for the purpose of achieving spectral flatness in the output frequency modulated clock. The circuit is combined with a multilevel error feedback noise shaping structure that provides the required Noise Transfer Function for the quantization noise but maintains a unity gain all pass signal transfer function. This arrangement offers minimal degradation of the in-band Signal-to-Noise-Ratio (SNR) at the cost of higher out-of-band noise.

    Abstract: A method for transmitting data on a configurable bus, comprising a number of physical links RD[z], comprises receiving input data on an input bus 10 at one or more of a number of data rates; selecting a number of the physical links on which the data is to be transmitted and a clock frequency at which the data is to be transmitted, based on information relating to the data rate of the input data and the number of links used on the input bus; and driving the physical links to transmit the data. The selection of transmission settings is intended to provide an optimal balance between bandwidth and power consumption. A receiver 20 which receives data in packets on a number of the physical links at a clock frequency, reformats the packets into groups 21 and transmits the reformatted data on an output bus 22 at one of a plurality of data rates, is also disclosed.
