  • Publication number: 20090285272
    Abstract: An integrated circuit device having a receive circuit is disclosed. The receive circuit generates first and second sets of samples of incoming symbols during first and second time intervals, respectively. A select circuit selects, based at least in part on the first set of samples, at least one sample from the second set to be output as a received data value. The integrated circuit device further includes a transmit circuit to generate an output symbol during a third time interval. The output symbol has an amplitude based, at least in part, on a transmit data value for which an output symbol was generated during a time interval prior to the third time interval.

  • Publication number: 20090175326
    Abstract: A receive circuit for receiving a signal transmitted via an electric signal conductor. A first sampling circuit generates a first sample value that indicates whether the signal exceeds a first threshold level, and a second sampling circuit generates a second sample value that indicates whether the signal exceeds a second threshold level. A first select circuit receives the first and second sample values from the first and second sampling circuits and selects, according to a previously generated sample value, either the first sample value or the second sample value to be output as a selected sample value.

  • Patent number: 7099424
    Abstract: A clock data recovery (CDR) circuit to recover a clock signal and data signal from an input signal. The CDR circuit includes a control circuit, a select circuit and a phase adjust circuit. The control circuit generates a first control signal according to a phase relationship between the input signal and a first clock signal. The select circuit is coupled to receive the first control signal from the control circuit and coupled to receive a second control signal. The select circuit is responsive to a select signal to select either the first control signal or the second control signal to be output as a selected control signal. The phase adjust circuit is coupled to receive the selected control signal from the select circuit, the phase adjust circuit being responsive to the selected control signal to adjust the phase of the first clock signal.
