  • Delay lock loop phase glitch error filter
    Patent number: 9083358
    Abstract: A method and apparatus is provided for providing a phase glitch error filter for a delay lock loop. The device comprises a delay lock loop to provide an output signal based upon a phase difference between a reference signal and a feedback signal. The delay lock loop comprises a filter unit to provide filtering of noise on a phase control signal to substantially reduce a false delay lock loop state.
    Type: Grant
