Abstract:
A system in one embodiment includes a global PLL circuit comprising multiple inputs, each input being for receiving an error signal associated with an individual channel; and a delay compensation circuit coupled to the global PLL circuit. A method in one embodiment includes receiving multiple error signals, each error signal being associated with an individual channel; applying one or more delay compensation signals to the error signals; and outputting phase error output signals for each of the channels.
