  • Secondary phase compensation assist for PLL IO delay aligning sync signal to system clock signal
    Patent number: 11664968
    Abstract: A line card receives a SYNC input signal and a first system clock signal. The line card generates a second system clock signal in a PLL and generates a SYNC output signal by dividing the second system clock signal in a divider circuit. The SYNC output signal is fed back as a SYNC feedback signal. The line card determines determining a closest edge of the first system clock signal to a transition of the SYNC input signal and determines a time difference between the closest edge of the first system clock signal and a transition of the SYNC feedback. The SYNC output signal is adjusted based on the time difference using a coarse adjustment by adjusting a divide ratio of the divider circuit and using a fine adjustment in the PLL based on a residue of a remainder of the time difference not accounted for by the coarse time adjustment.
