Abstract
Some embodiments provide a clock and data recovery (CDR) system to recover clock and data information from an analog signal. The CDR system may include an integral path and a proportional path that are part of an integral-proportional control loop. The integral path may be used to track frequency changes in a clock signal that is embedded in the analog signal, while the proportional path may be used to track phase changes in the clock signal that is embedded in the analog signal. The proportional path may be executed at a first clock frequency, while the integral path may be executed at a second clock frequency that is lower than the first clock frequency to reduce the power consumption of the CDR system.
