Abstract:
A cable connector assembly for a cable carrying high speed data signals at a desired rate, the data rate having a fundamental frequency, the data signals including multiple attenuated frequency components defining an attenuation characteristic curve over an operating frequency range of the data signals, the connector assembly comprising:a plug adapted to be mounted to a cable; a receptacle connected to the plug; and an equalization circuit board conveying data signals at a data rate over data paths between the plug and receptacle, said circuit board attenuating frequency components below a cut-off frequency without introducing equalization attenuation into frequency components above the cut-off frequency, said cut-off frequency being between one-half of a fundamental frequency of the data rate and a second harmonic frequency of the data rate, said equalization circuit board maintaining at a cable connector assembly, an amplitude signal-to-noise ratio for the data in the equalized high speed data signal at a value such that an amplitude of noise substantially exceed 25% of an amplitude of the data signal for any length of cable.
