Abstract
A circuit and method for evaluating serializer deserializer (SERDES) performance that is particularly advantageous when the SERDES has a decision feedback equalizer (DFE). In one embodiment, the circuit has a data processing path and an operational feedback loop coupled to said data processing path and containing an equalizer, perhaps a DFE. In that embodiment, the circuit includes an eye scanning circuit coupled to said data processing path but separate from said equalizer and configured to measure at least one dimension of an eye relative to which said equalizer is configured for operation without substantially affecting said operation.
