Title: Differential signal reception device and method for supporting variable threshold levels

Abstract: A differential signal reception device and method for supporting variable threshold levels. The device flexibly makes an input to the decision circuit appear to an outside driving circuit as if the decision circuit were a purpose-built input network supporting a fixed impedance input into either a floating or fixed DC termination voltage. The device further allows the internal decision process to support a variable threshold level when deciding logical 1/0 values and to attenuate the users input signal range for the purpose of making sure the range of the user's signals do not exceed the operating range of readily available decision circuit (limiting amplifier) integrated circuits.
