Abstract
A receiver system that includes a clock and data recovery (CDR) system for aligning a local clock signal to an incoming data signal to extract correct timing information from the incoming data signal is provided. A timing error detector generates an output phase error signal representing the phase difference between the incoming data signal and the local clock signal. The timing error detector determines the phase difference according to recovered symbols and the difference between the recovered symbols and digital samples of the incoming data signal. The digital samples of the incoming data signal include intersymbol interference. The output timing information is suitable for aligning the local clock signal to the incoming data signal.
