摘要： A cable driver (301) for driving a single ended transmission medium such as a coaxial cable (115) comprising a core (120) and a shield (121) comprises a differential driver (104, 377) comprising a first output (151) for putting a first signal to the core (120) of the single ended transmission medium (115), a second output (152) for putting a second signal to the shield (121) of the single ended transmission medium (115) through a termination resistor (118) having an impedance close to the characteristic impedance (Z0) of the single ended transmission medium (115), and a third output (153) for putting a transmit ground supply signal (GNDT), local to the differential driver, to the shield (121) of the single ended transmission medium (115) through a first high frequency low impedance path (112). In use, the current through the third output (153) will be substantially the inverse of the common mode current through the first and second outputs (151, 152). Hence both the common mode current and its inverse are provided to the single ended transmission medium (115). They cancel each other out and thus advantageously low EMI emissions occur.

摘要： A method of improving electrical isolation between a first circuit and a second circuit sharing a common substrate having an effective dielectric constant greater than that of air. The first and second circuits are spaced apart and separated from one another by an intermediate portion of the substrate. The method includes removing a portion of the intermediate portion to replace the portion removed with air thereby reducing the effective dielectric constant of the intermediate portion. By reducing the effective dielectric constant of the intermediate portion, electrical isolation between the first and second circuits is improved thereby reducing crosstalk between the first and second circuits. In particular implementations, the method may be used to reduce alien crosstalk between adjacent communication outlets in a patch panel.
