Abstract:
A data signaling apparatus, comprising:first and second input nodes for receiving an input differential data signal; first and second output nodes; a differential amplifier coupled to the input nodes and the output nodes that provides an amplified differential data signal on the output nodes in response to the received input differential data signal, the differential amplifier including: a first feedback resistor coupled between the first input node and the first output node, a second feedback resistor coupled between the second input node and the second output node, a first conduction path coupled to the first output node and controlled by a first transistor coupled to the first input node, and a second conduction path coupled to the second output node and controlled by a second transistor coupled to the second output node, wherein the amplified differential data signal is established between the output nodes in accordance with a relative current flowing in the first and second conduction paths based on the received input differential data signal established between the input nodes; and a clamping resistor coupled between the input nodes and in a current path with the first and second feedback resistors.
