Abstract: An apparatus is provided which comprises: an amplifier; a first slicer coupled to the amplifier; a de-serializer coupled to an output of the first slicer; a multiplexer which is operable to select one of data or a test signal for the amplifier; a filter coupled to an input of the multiplexer to provide test signal; and a frequency modulator coupled to the filter, wherein the frequency modulator is operable to modulate frequency of the test signal. An apparatus is also provided which comprises: an analog multiplexer having a first input to receive serial data, and a second input; an analog front-end (AFE) coupled to an output of the analog multiplexer; and a filter coupled to the second input of the analog multiplexer.
