<p>A system, apparatus and method are arranged for monitoring an input signal for a line driver and determining if a valid data signal is present. When the input signal is determined to be an invalid data signal, an offset is introduced into the input stage of the line driver to prevent noise induced toggling of the output of the line driver. When the input signal is determined to be a valid data signal, the offset is removed from the input stage since inclusion of the offset can introduce undesirable duty cycle distortion in the output of the line driver. By dynamically adding or removing the offset from the input stage of the line driver, invalid signals are prevented from toggling the output of the line driver while preserving a clean data transmission for valid signals.</p> |
