    摘要: In an integrated decision feedback equalizer and clock and data recovery circuit one or more flip-flops and/or latches may be shared. One or more flip-flops and/or latches may be used in retiming operations in a decision feedback equalizer and in phase detection operations in a clock recovery circuit. Outputs of the flip-flops and/or latches may be used to generate feedback signals for the decision feedback equalizer. The output of a flip-flop and/or latches may be used to generate signals that drive a charge pump in the clock recovery circuit.

    摘要: Systems and methods for optimizing operation of a transceiver device are disclosed. The method may include parallel processing an input signal through a first path having a first frequency response and a second path having a second frequency response. The second frequency response may be higher than the first frequency response. Signals from the first and second paths may be combined, creating an output signal having a desired gain and frequency. The parallel processing may adjust a gain of at least one of the first path and the second path. The parallel processing may equalize at least one of the first frequency response and the second frequency response. The input signal may be from a 10 GBit Ethernet channel and/or a Fibre channel.

    摘要: Aspects of the invention may provide a method and system for adjusting a gain and/or a frequency response of an input signal for a multimode PHY device. A signal divider may apportion the input signal into a gain adjustment signal and/or an equalization adjustment signal upon receipt of the input signal. A signal adjuster coupled to the signal divider may adjust a gain of the apportioned gain adjustment signal within the multimode PHY device. An equalizer coupled to the signal divider may be configured to equalize the equalization adjustment signal within the multimode PHY device. A summer coupled to the equalizer and signal adjuster may be adapted to sum the adjusted adjustment signal and the equalized equalization adjustment signal within the multimode PHY device to create an output equalized signal having a desired gain and/or frequency response.

    摘要: Aspects of the invention may provide a method and system for adjusting a gain and/or a frequency response of an input signal for a multimode PHY device. A signal divider (704) may apportion the input signal into a gain adjustment signal and/or an equalization adjustment signal upon receipt of the input signal. A signal adjuster (702) coupled to the signal divider (704) may adjust a gain of the apportioned gain adjustment signal within the multimode PHY device (130). An equalizer (706) coupled to the signal divider (704) may be configured to equalize the equalization adjustment signal within the multimode PHY device (130). A summer (708) coupled to the equalizer (706) and signal adjuster (702) may be adapted to sum the adjusted adjustment signal and the equalized equalization adjustment signal within the multimode PHY device (130) to create an output equalized signal (712) having a desired gain and/or frequency response.
