Abstract
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 embodied in a first integrated circuit, the clock and data recovery circuit being configured to re-clock a data stream. The system also includes an automatic rate detection system embodied in a second integrated circuit, where the first integrated circuit is in data communication with the second integrated circuit. Also, the automatic rate detection system is configured to determine a data rate 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.
