SYSTEM AND METHOD FOR PROGRAMMABLY ADJUSTING GAIN AND FREQUENCY RESPONSE IN A 10-GIGABIT ETHERNET/FIBRE CHANNEL SYSTEM

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.
