  • Phase transport with frequency translation without a PLL
    Patent number: 11777703
    Abstract: A line card in a network box receives a SyncE clock signal and an input synchronization (SYNC) signal. A phase-lock loop (PLL) in the line card receives the SyncE clock signal as a reference clock signal and generates an output SyncE clock signal. The line card regenerates a SYSCLK signal using a digitally controlled oscillator that receives a timing signal from the SyncE PLL and receives a control signal from control logic on the line card. The frequency and phase information contained in the SYNC signal is utilized to control the DCO. The SYSCLK signal is divided to generate an output SYNC signal. The control logic uses the time difference between the input SYNC signal and a SYNC feedback signal to control the DCO to provide a zero delay SYNC output signal. The output SYNC signal and the SYSCLK signal control a time of day counter in the line card.
