Abstract:
A serial input/output method and receiver include an receiver portion to receive an analog differential serial input and sample the input to provide data and error signals, an equalization feedback loop responsive to the data and error signals to adjust the receiver portion, a phase feedback mechanism separate from the equalization feedback loop to provide a phase error, and a clock data recovery block coupled to receive the phase error to perform timing recovery for the receiver portion independent of the equalization feedback to adjust the sampling.
