An adaptive equalizer system for use in {TAIL ~ a serial communication link} uses timing information generated by a phase detector of a clock and data recovery circuit of the serial communication link and a frequency pattern of the recovered data to determine whether the data received over {HEAD ~ the serial communication link} is over equalized or under equalized
