Abstract (en)
[origin: DE19842818A1] A synchronous circuit (M) includes a clock input (CLKE), a clock-pulse generator (G) for generating a second clock pulse (CLKINT) locked in phase with the first clock pulse (CLKE), an input connected to the clocked input and a clock output for outputting the second clock pulse. The clock output of the generator (G) is connected to a control input of a data transmission unit (DRV) and serves to output data from, or to read data into, an integrated circuit, largely in sync with the first-clock (pulse) (CLKE). The clock-pulse generator has at least two series-connected control loops (1,2) for controlling the phase-angle of the second clock (pulse) (CLKINT). A deactivating unit (AKT) deactivated control of the first control loop (1) during transmission of data through the data transmission unit (DRV) so that control of the phase-angle of the intermediate clock (pulse) (CLKi) is interrupted.
