Abstract: An active bidirectional splitter (212) for transmission and reception of data signals over a single ended transmission medium (105) comprises an input port (150), an output port (152) and a differential combined input/output port (151), a first differential output driver (115) for receiving an input signal (144) from the input port (150) and transmitting this signal to the differential input/output port (151), a second differential output driver (116) for receiving the input signal (144) from the input port (150), a first averaging circuit (121) for averaging the differential signal (146, 147) at the differential input/output port (151), a second averaging circuit (120) for averaging the differential signal (144, 145) at the output of the second differential output driver (116), and a receiver (117) for receiving both averaged signals (118, 119) from the first averaging circuit (121) and the second averaging circuit (120) and for generating therefrom an output signal on the output port (152).

Abstract: 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).

Abstract: The present invention is related to an adaptive equalizer comprising multiple tuning circuits that generate tuning signals. Each tuning signal can typically induce higher frequency gain up to a limited level, e.g. +5 dB, at the upper data frequency for compensation of high frequency losses in the connected transmission channel. Several tuning signals can tune one adaptive amplifying compensation stage. In its adaptive amplifying compensation stage the tuning signal can generate through its tuning function, non-linear small-signal and large-signal transfer behavior. However, by limiting the amount of higher frequency gain to maximum +8 dB per tuning function, and by having only one tuning function active at a time the resulting deterministic fitter remains tolerable. Several adaptive amplifying compensation stages introducing non-linear effects in the compensation behavior and their tuning functions are disclosed. Especially at low power supply voltage the merits of the present invention become apparent.
