A clock generation circuit comprises an internal clock signal source providing an internal clock signal and a synchronization device for synchronization the internal clock signal with a reference clock signal provided externally from the clock generation circuit. The synchronization device comprises n delay locked loop circuits, n being an integer greater than 1, each delay locked loop circuit having a clock input for receiving the internal clock signal and a clock output for providing an output clock signal with an individual phase shift that is adjustable. The synchronization device further comprises a multiplexer having n inputs and an output wherein each of the n inputs is connected to an output of one of the n delay locked loops and a control circuit. The control circuit is adapted to adjust at least one of the delay locked loop circuits for providing an individual phase shift according to a current phase shift and to select that input of the multiplexer that receives an output clock signal of the adjusted delay locked loop circuit that is synchronized in frequency and phase with the reference clock signal, wherein the output of the multiplexer provides that output clock signal as synchronized clock signal, and wherein the control circuit is adapted to toggle between the n delay locked loop circuits, in a way that the phase of the internal clock signal is successively shifted according to the current phase shift between the internal clock signal and the reference clock signal.

An electromechanical switch is described, which comprises a conductive body and a plurality of carbon nanotubes being separate to each other, each of the carbon nanotubes being connected to at least one common terminal electrode with at least one of its ends, wherein in an open state of the switch each of the carbon nanotubes substantially projects along a surface of the conductive body and keeps up a gap to said surface, and wherein in a closed state of the switch at least one carbon nanotube is bend in a direction of the surface to close an electrical contact between said terminal electrode and the conductive body. The size of the gap between the respective carbon nanotube and the surface is different for each one of the plurality of carbon nanotubes.

State of the art processor systems, esp. in embedded systems, are not able to process data under real-time conditions especially with throughput rates near 10 Gbps. So, when using interfaces like PCI Express (PCIe) or Infiniband or 10 G-Ethernet for 10 Gbps data throughput, special data-paths have to process the high throughput rate data. But tasks like connection management or time uncritical control messaging are better manageable by a processor. According to the invention it is proposed a kind of multiplexer architecture that is needed to split between control and data-path access for a PCI Express based architecture.
