Abstract:
An apparatus including a control loop for controlling a multilevel detecting of an input data signal, comprising:a data signal peak detection circuit that receives a plurality of peak reference signals, receives and detects said input data signal, and provides a plurality of peak parameter signals which indicates whether said input data signal has transcended a plurality of predetermined signal levels including predetermined minimum and maximum signal levels; a signal processing circuit, coupled to said data signal peak detection circuit, that receives and processes said plurality of peak parameter signals and provides a first processed parameter signal which indicates whether said input data signal has transcended one of said predetermined minimum and maximum signal levels, and a second processed parameter signal which indicates which one of said predetermined minimum and maximum signal levels said input data signal has transcended; and a peak reference generation circuit, coupled to said signal processing circuit and said data signal peak detection circuit, that receives and processes said first and second processed parameter signals and provides said plurality of peak reference signals.
