ABSTRACT:
A dynamic phase selector phase locked loop circuit includes: an A/D converter for receiving an input to be sampled; a phase detection circuit for determining the phase error between the input signal and a clock signal; a clock circuit, responsive to the phase detection circuit, for providing the clock signal to the A/D converter for timing the sampling of the input signal; the clock circuit including a delay circuit having a number of delay taps; and a phase selector circuit, responsive to the phase detection circuit, for initially gating the clock signals to the A/D converter from the clock circuit, and enabling one of the delay taps to dynamically adjust the phase of the clock signal and reduce the initial phase error.
