Abstract

See full text

Methods and systems for conditioning wireline communications to remove intersymbol interference are provided that used adaptive equalization. The method and systems include using a digital finite state machine to control two feedback loops that adjust the gain and power of the input signal relative to a supplied reference. The eye height of the input signal is conditioned by a gain feedback loop so that signal equalization can be performed in a known state. The digital finite state machine allows the loops to be flexibly run in sequence or concurrently. The adaptation functions can be shut off when adequate signal equalization has been achieve, thus saving power.
