Abstract
A serial data receiver includes an amplitude path including a first signal conditioner that adds a first offset or subtracts a second offset based on a selection input, a preamp configured to receive a signal from a transmitter and provide an input signal to the amplitude path, an amplitude latch coupled to the amplitude path, a data latch having a data output and a decision feedback equalization (DFE) logic block coupled to the first conditioning element and the data output and configured to generate the selection output based on the data output of the data latch.
