AUTOMATIC DETECTION OF DATA RATE CHANGES

摘要

Various systems and methods for automatic data rate detection are provided. In one embodiment, a system is provided that includes a clock and data recovery circuit (123) embodied in a first integrated circuit (109), the clock and data recovery circuit (123) being configured to re-clock a data stream. The system also includes an automatic rate detection system (113) embodied in a second integrated circuit (116), where the first integrated circuit (109) is in data communication with the second integrated circuit (116). Also, the automatic rate detection system (113) is configured to determine a data rate change of the data stream upon identifying a transition in the data rate of the data stream based upon the state of the at least one status flag received from the clock and data recovery circuit (123).
