Adaptive real-time control of de-emphasis level in a USB 3.0 signal conditioner based on incoming signal frequency range
摘要：
An apparatus comprises a differential equalizer having: a) a first differential input, b) a second differential input, c) a first differential output, and d) a second differential output; a frequency detector coupled to the first and second differential inputs; an amplifier coupled to a first differential output and a second differential output of the differential equalizer; and a logical combiner having a first input coupled to an output of the frequency detector and an output coupled to a control input of the amplifier, wherein the logical combiner can mask at least one received de-emphasis parameter.
