ABSTRACT:
Data synchronization is achieved in devices which transmit and/or receive audio and/or video data through the staged locking of phase locked loops. According to an exemplary embodiment, a transmitter includes a serial data source. An encoder provides encoded data and includes a first PLL. A controller includes a second PLL which enables generation of a clock signal. The controller is coupled between the serial data source and the encoder for providing the clock signal to the encoder. The first PLL of the encoder locks to the clock signal.
