The invention relates to a controller for generating control signals (evload_o, odload_o, st_chgclk_o, clk_o , clkorfiford_i) synchronous with a continuous clock signal (clk_hr_i) input to it for a device (1) to be controlled synchronously with the clock signal (clk_hr_i), wherein the controller (SE) has: register means for registering at least one set signal (st_load_i, st_fiford_i), comprising a plurality of bit positions, counting means for counting edges of the clock signal (clk_hr_i) depending on one or a plurality of set signals respectively registered in the register means, and synchronization and output means for synchronizing a value counted by the counting means with the clock signal (clk_hr_i) and the registered set signal and outputting at least one of the control signals, wherein the register means, the counting means and the synchronization and output means are configured and connected to one another in such a way that the output control signal(s), depending on the respectively registered set signal, occupies (occupy) one of a plurality of temporal positions with a respective phase difference of an integral multiple of half a clock cycle synchronously with the leading or trailing edge of the clock signal. The controller can be applied in particular for controlling the synchronous parallel-serial converter for converting a parallel input signal comprising k bit positions into a serial output signal sequence synchronously with the clock signal (clk_hr_i), which converter is provided in a transmitting circuit in the interface circuit of a very fast DDR DRAM semiconductor memory component of the coming memory generation (e.g. DDR4).
