摘要： A radio frequency antenna system and high-speed digital data link are disclosed to, among other things, reduce electromagnetic interference (“EMI”) at relatively high data rates while reducing the manufacturing complexities associated with conventional data links. In one embodiment, a radio frequency (“RF”) antenna system includes an antenna and an RF radio coupled to the antenna for receiving wireless RF signals. In particular, the RF radio is configured to digitize RF signals at a fixed data rate to form digitized data signals and to apply the digitized data signals at a variable data rate to a high-speed digital link. The variable data rate distributes the signal energy of the digitized data signals over one or more bands of frequencies, thereby beneficially altering an EMI spectral profile describing emissions that develop as the digitized data signals are transported through a channel.

摘要： A system, method and system are disclosed for using a variable frequency clock generator to synchronize an average data rate over intervals of time in a variable clock domain to make it equal to a fixed data rate in a fixed clock domain while reducing electromagnetic interference, among other things. In various embodiments, setting the data rates equal to each other minimizes storage used to transition data signals between clock domains. In one embodiment, a variable frequency clock generator includes a phase modulator configured to form a variable frequency clock. Also, the variable clock generator is configured to maintain an average frequency over specific periods of time for the range of discrete frequencies. The phase-offset controller sets an average clock having substantially no offset between a fixed data rate in the fixed clock domain and an average data rate in the variable clock domain.
