  • Delay locked loop based circuit for data communication
    Patent number: 6466615
    Abstract: An apparatus including a plurality of quantizers each configured to compare a selected threshold signal with an input signal and generate an output, a multiplexer, coupled to the plurality of quantizers, that selects one of the plurality of quantizer outputs according to a frequency response, and a multiplication-accumulation (MAC) unit, coupled to the multiplexer, the MAC to generate an output based on a previously selected one of the quantizer outputs according to the frequency response.
    Type: Grant

    Date of Patent: October 15, 2002
    Assignee: Intel Corporation
    Inventor: Hongjiang Song
  • Locked loop circuit
    Publication number: 20020141527
    Abstract: A system includes a locked loop circuit and a processor. The processor is coupled to the locked loop circuit to control the locked loop circuit and perform at least one other function in the system not related to the control of the locked loop circuit.
