Abstract
A receiver to recover data encoded at high speed in a signal over a serial communication channel. A static phase determination circuit indicates whether the signal is early, late or neutral relative to a sampling clock. The sampling clock is used to oversample the signal to generate multiple samples. A token analyzer examines the transitions around a current symbol to determine any short term phase shifts of the boundaries between symbols. The short term phase shifts and the static phase together may be used to accurately select the samples representing the symbols without requiring extensive processing.
