CLOCK AND PHASE ALIGNMENT BETWEEN PHYSICAL LAYERS AND CONTROLLER

An integrated circuit (IC) for clock and phase aligning and synchronization between physical (PHY) layers and a communications controller is provided. The IC includes a clock multiplier configured to multiply a frequency of the clock signal from a plurality of PHY layers to match a frequency of a clock signal of the controller, wherein the clock signal from the plurality of PHY layers is less than the frequency of the clock signal of the controller. IC support circuitry is configured to provide the multiplied clock signal to the controller. The IC includes a first clock divider configured to divide the frequency of the multiplied clock signal and to output the divided clock signal to the controller. The IC includes a phase alignment circuit configured to align phases of one or more data signals based on a phase of the clock signal and a phase of the multiplied clock signal.
