The present disclosure discloses an adjustable electric control equalization circuit used for cable television networks. The disclosed adjustable electric control equalization circuit includes one or more electric control equalization modules with adjustable slopes, a control module, and one or more compensation modules. The control module and the one or more electric control equalization modules are electrically connected to control slope change of the one or more electric control equalization modules. The control module and the one or more compensation modules are electrically connected to generate compensation signals based on the slope change of the one or more electric control equalization modules. An output of the one or more electric control equalization modules is electrically connected to an input of the one or more compensation modules to output a combined signal of a sum of signals outputted from the electric control equalization module and the compensation module.

An equalizer circuit of a particular equalization stage of a equalizer circuit is omitted, and input signals that would have otherwise been received at the omitted equalization circuit bypass the equalization stage and are instead processed at an equalizer circuit included at the next stage. Thus, a subset of the received frequency-domain signals can be processed by equalizer circuits at a first stage, while the remaining received frequency-domain signals bypass the first stage and are processed at an equalizer circuit included at a second stage.

An integrated circuit may include receiver circuitry that receives data from an external device. Such receiver circuitry may include, among other things, equalization circuitry that may reconstruct the received data before transmitting the received data to other parts of the integrated circuit. The receiver circuitry may include two different equalization circuits. A first equalization circuit may perform equalization on the received data to generate a first equalized output while a second equalization circuit may generate a second equalized output. The receiver circuitry may further include an amplifier circuit that selectively amplifies either the first or second equalized output from the respective first and second equalization circuits based on the data rate of the received data.
