Abstract
A phase locked loop for synchronizing decoding clocks with encoding clocks in a Moving Picture Experts Group (MPEG) system. The phase-locked loop circuit includes a voltage controlled oscillator for converting a decoding clock into an encoding clock, a register unit for storing multiplexing program clock reference signals, each input with a desired number of bits, a counter being initialized by a first program clock reference signal output from the register unit, thereby generating a local program clock reference signal, and a phase error control unit for combinationally operating the program clock reference signal stored in the register unit and the local program clock reference signal, thereby generating a phase error signal for controlling the voltage controlled oscillator.
