  • Clock and data recovery circuit having gain control
    Patent number: 7620136
    Abstract: A clock and data recovery circuit includes a phase detector configured to compare a phase of a data signal to a phase of a sampling clock to provide a phase error signal, a gain stage configured to apply a gain to the phase error signal to provide an amplified phase error signal, and a filter configured to filter the amplified phase error signal to provide a phase correction signal. The circuit includes a gain controller configured to adjust the gain of the gain stage in response to the phase correction signal, and a clock generator configured to provide the sampling clock based on the phase correction signal.
