Abstract

A clock signal generator for generating clock signals to an integrated circuit. The clock signal generator comprises a delay-locked loop adapted to generate a plurality of mutually delayed clock phases based on a reference clock signal. The delay-locked loop is further adapted to select one of the plurality of clock phases as an output signal of the delay-locked loop in response to a first control signal, wherein said output signal is a first clock signal. The clock signal generator further comprises an inverter arranged to generate an inverse of the output signal and a multiplexer unit arranged to, in response to a clock-invert signal, forward either the output signal or the inverse of the output signal as a second clock signal.
