An apparatus for providing a signal for transmission via a signal line includes a controller circuit having an output for a signal indicating whether the signal line is or will be in an inactive state and a switching circuit coupled to the controller circuit and having an output coupled to the signal line. The output is switched between different signal levels, if the signal indicates that the signal line is in an inactive state.

Apparatus and method for providing a signal for transmission via a signal line

An apparatus being connectable as a latch stage into a asynchronous latch chain comprises a reception interface, wherein upon receipt of the first signal at the reception interface, the apparatus switches to one of the first power saving mode and a second power saving mode, depending on the second signal at the reception interface and wherein the apparatus offers a first power consumption and a first wake-up time in the first power saving mode, and a second power consumption and a second wake-up time in the second power saving mode.

Apparatus and method for switching an apparatus to a power saving mode

An apparatus interfaces a first circuit using a first supply voltage and a second circuit using a second supply voltage different from the first supply voltage. The apparatus includes a driver circuit having a driver network comprising driver supply voltage terminals connected to controllable switches. The controllable switches include resistive elements or are separated from resistive elements. A receiver circuit has a receiving network comprising a resistive element and receiver supply voltage terminals and a connection line connecting the driver circuit and the receiving circuit. The controllable switches have two switch configurations, a first switch configuration resulting in a high voltage on the connection line and a second switch configuration resulting in a low voltage on the connection line.
