Patent abstract
The present invention provides a system, apparatus and method for recovering a client signal clock. The present invention is able to more effectively remove jitter within a clock signal by providing a phase shifting element in the feedback of a PLL system to compensate for sudden changes in an input reference clock. The PLL system provides flexible clock recovery so that it can accommodate various payload types because it extracts a client clock signal independent of a corresponding justification count number.
