    • A clock signal desired to be transmitted to various components of the electronic system is combined with a noise signal to generate a spread spectrum clock signal which, in turn, is distributed with an associated reference signal to selected components of the system using two-channel communication links. A receiving circuit within each of the selected components recovers the original clock signal from the spread spectrum clock signal and its associated reference signal. In one embodiment, the clock signal is combined with the noise signal in an exclusive-OR logic gate to generate a spread spectrum clock signal which is distributed to receiving components using a first channel. The noise signal is transmitted as the reference signal using the second channel. The two channel signals are combined in an exclusive-OR gate of one or more receiving circuits to recover the clock signal. In other embodiments, transmission of the clock signal is alternated between the two channels in accordance with the logic state of the noise signal. Here, the two channel signals are combined in an OR logic gate of each receiving circuit to recover the clock signal.

    • A circuit to control the edge rate of a digital signal includes a conductor to carry a digital signal. A first capacitive component has a first node and a second node, with the second node being coupled to the conductor. A first phase control circuit has a first input node coupled to the conductor, a second input node to receive a first enable signal and an output node coupled to the first node of the first capacitive component. The first phase control circuit processes the digital signal from the conductor and the first enable signal to produce a control signal at the output node to control the edge rate of the digital signal. The first phase control circuit produces the control signal in one of at least two different phase relationships with the digital signal according to a state of the first enable signal. The control signal may be in phase with the digital signal or complementary to the digital signal.

    • A high frequency bus system which insures uniform arrival times of high-fidelity signals to the devices on the high frequency bus, despite the use of the bus on modules and connectors. A high frequency bus system includes a first bus segment having one or more devices connected between a first and a second end. The first bus segment has at least a pair of transmission lines for propagating high frequency signals and the devices are coupled to the pair of transmission lines. The high frequency bus system also includes a second bus segment which has no devices connected to it. The second bus segment also has at least a pair of transmission lines for propagating high frequency signals. The first end of the first segment and second end of the second segment are coupled in series to form a chain of segments and when two signals are introduced to the first end of the second bus segment at the substantially the same time, they arrive at each device connected to the first bus segment at substantially the same time. Also, when two signals originate at a device connected to the first bus segment at substantially the same time, they arrive at the first end of the second bus segment at substantially the same time. Uniform arrival times hold despite the use of connectors to couple the segments together, despite the segments being located on modules, without the need for stubs, despite the presence of routing turns in the segments and despite the type of information, such as address, data or control, carried by the signals.
