Abstract
An analog transmit side crosstalk cancellation system is disclosed which is located at or near the connector of a communication channel, cable, or backplane. When configured as a connector, multiple signal paths are provided within the cancellation system. Input nodes and output nodes provide access into the connector of a received signal and out of the connector for processed signals. The crosstalk canceller comprises a delay, a filter, and an amplifier. These elements operate in conjunction to generate crosstalk cancellation signals. For a particular received signal, cancellation signals are combined therewith from one or more adjacent channels. The crosstalk cancellation system may be configured as part of a connector or an intermediary device between the communication device or card and conductors. The connector may be attached to the communication device or as part of the cable.
