Abstract
Methods and apparatus are provided for data rate detection using a data eye monitor. The data rate is one of a plurality of data rates comprising a base rate and one or more divide-by-N multiples of the base rate, where N is an integer. The data rate of a received signal is detected by sampling the received signal; comparing the samples for a plurality of full rate data eyes associated with the received signal to determine if there is a mismatch between at least two predefined samples; and detecting the data rate by evaluating the comparison based on predefined criteria. The comparison can be performed by an exclusive or (XOR) logic gate for samples of at least two adjacent data eyes of a given rate.
