Abstract
A timing synchronizing circuit with a phase locked loop. A multiplexor is employed to cause the phase locked loop to alternate between a self-excited mode for maintaining the frequency of a recovered timing signal and a mode in which state transitions of a baseband data signal are compared with the phase locked loop feedback signal to adjust the frequency of the recovered timing signal.
