<p>A communication system, such as a digital cable network, achieves synchronization using data rate synchronization, clock frequency synchronization, or clock recovery synchronization techniques. The communication system includes a conversion clock at a transmitter and a conversion clock at a receiver. The data rate synchronization techniques adjust data rates by resampling digital data sent from the transmitter to the receiver to compensate for frequency variations in the conversion clocks. The clock frequency synchronization techniques use time stamps to adjust the receiver conversion clock frequency to substantially match the transmitter conversion clock frequency. The clock recovery techniques use a reference clock to adjust the transmitter conversion clock frequency and the receiver conversion clock frequency to be approximately the same.</p> |
