Abstract
The invention relates to a circuit and method for receiving a signal of which—at the receiver end—the frequency is basically unknown. By sampling the data and deriving the frequency of the signal (or actually: the data rate of the data carried by the signal) and setting a phase locked loop in the receiver to the derived—estimated—circuit, the receiver can very quickly tune in to the frequency of the signal. Hence, no embedded or accompanying clock is required for the signal. Oversampling of the signal by the receiver front end is preferred, though.
