Abstract:
An apparatus for transmitting a data stream, comprising:framing circuitry designed to generate a first sequence of data frames each having a first duration, the first sequence of data frames corresponding to a first data rate, the framing circuitry being programmed to receive and organize the data stream into a second sequence of data frames each having the first duration, the second sequence of data frames corresponding to a selected one of a plurality of equivalent data rates and a selected one of a plurality of framed data rates, each of the equivalent and framed data rates being lower than the first data rate; modulation circuitry for modulating the second sequence of data frames and transmitting the modulated second sequence of data frames at the selected framed data rate; first clock circuitry operable to provide any of a first plurality of clock signals to the framing circuitry, each of the first plurality of clock signals corresponding to one of the plurality of equivalent data rates; and second clock circuitry operable to provide any of a second plurality of clock signals to the modulation circuitry, each of the second plurality of clock signals corresponding to one of the plurality of framed data rates.
