Abstract: The present invention is directed to integrated circuits. In a specific embodiment, high frequency signals from an equalizer is directly connected to a first pair of inputs of a sense amplifier. The sense amplifier also has a second pair of inputs, which can be selectively coupled to output signals from a DAC or high frequency loopback signals. There are other embodiments as well.
