    摘要: A phase detector and corresponding method. The phase detector detects a transition of a first signal and generates an output signal having a first value if a transition of a second signal occurs before the transition of the first signal and having a second value if the transition of the second signal occurs after the transition of the first signal. The output signal is maintained at the generated value until another transition of the first signal is detected. A strobe signal may be used to strobe the output signal.

    摘要: Method and apparatus for a feed forward equalizer for a communication system are described wherein an equalizer may comprise a tapped filter having multiple filter multipliers, a correlator having multiple correlator multipliers, and a set of shared delay elements to connect to the filter multipliers and the correlator multipliers. Each delay element may include multiple delay stages. A first delay stage may receive an input data signal and output a first delay signal to one of the correlator multipliers, and a second delay stage may receive the first delay signal and output a second delay signal to one of the filter multipliers. Other embodiments are described and claimed.
