Abstract
A digital phase-lock loop network that provides input and output clock signals to a digital data receiving system generally, and particularly to a data buffer contained therein, is disclosed. The digital phase-lock loop network provides bit-clock synchronization using a fixed input clock and an output clock having a variable frequency that is adjusted to correspond to the average input rate of the data samples into the data buffer. The digital phase-lock loop network allows the data buffer to be operated as a temporary storage device maintaining a nominal number of data samples therein at all times by avoiding any overflow and underflow data handling conditions that may otherwise cause loss of data. The digital phase-lock loop network of the present invention is particularly suited for the Eureka-147 system which has become a worldwide standard for digital audio broadcasting (DAB) technology.
