Abstract
A spread spectrum generator module is configured to provide data for spreading frequency spectra of at least first and second lower bandwidth asynchronously clocked communication links. A packet scheduling module aggregates the two (or more) lower bandwidth links into a higher bandwidth link or interface. The frequency spectra of the lower bandwidth links are spread in accordance with the data for spreading the frequency spectra. A downstream disaggregation element filters high frequency noise resulting from the spreading of the spectra.

A method comprising the steps of:
- spreading a frequency spectrum of at least a first lower bandwidth asynchronously clocked communication link;
- spreading a frequency spectrum of at least a second lower bandwidth asynchronously clocked communication link;
- and
- subsequent to said steps of spreading said frequency spectra of said at least first and second lower bandwidth asynchronously clocked communication links, aggregating said at least first and second lower bandwidth asynchronously clocked communication links into one of a higher bandwidth link and a higher bandwidth interface, using multiplexing equipment.
An apparatus comprising:
- a spread spectrum generator module configured to provide data for spreading frequency spectra of at least first and second lower bandwidth asynchronously clocked communication links;
- and
- a packet scheduling module configured to aggregate said at least first and second lower bandwidth asynchronously clocked communication links into one of a higher bandwidth link and a higher bandwidth interface, with said frequency spectra of said at least first and second lower bandwidth asynchronously clocked communication links spread in accordance with said data for spreading said frequency spectra.
An integrated circuit including at least one apparatus, said at least one apparatus comprising:
- a spread spectrum generator module configured to provide data for spreading frequency spectra of at least first and second lower bandwidth asynchronously clocked communication links;
- and
- a packet scheduling module configured to aggregate said at least first and second lower bandwidth asynchronously clocked communication links into one of a higher bandwidth link and a higher bandwidth interface, with said frequency spectra of said at least first and second lower bandwidth asynchronously clocked communication links spread in accordance with said data for spreading said frequency spectra.
