Abstract: A clock generator serves to generate a stable frequency system clock for a clock-controlled electronic device. To ensure that the system clock causes only little electromagnetic interference to nearby electronic equipment, the system clock is modulated with respect to a reference clock by means of a phase modulator controlled by a random signal source which is noise colored by means of a weighting device.

Abstract: Spurious-emission-reducing terminal configuration for an integrated circuit, particularly a monolithic integrated circuit, operable within an unshielded board network, the integrated circuit being divided into a first subcircuit, which has essentially radio-frequency current components, and a second subcircuit, which has essentially low-frequency current components, the separation also extending to the internal supply lines and supply contact pads. The second subcircuit includes driver circuits which are connected to I/O lines on the board network. On the grounded side, the first and second supply current paths are interconnected within the integrated circuit by a low-resistance and low-inductance connection to establish a ground point.
