Abstract:
A skew control loop circuit for controlling a skew between a plurality of digital signals, and a semiconductor device, and a method of operation, for the same, may be provided. The skew control loop circuit comprises a skew detector for detecting a phase difference between the digital signals, a skew control circuit adapted for controlling an operation of the skew control loop circuit. The skew control circuit is operable in a first operating mode and in a second operating mode. The skew control loop circuit comprises also an enable input of the skew detector, wherein the enable input is adapted for receiving an enable input signal, generated by the skew control circuit, wherein the enable input is adapted for selectively enable or disable a phase detection operation of the skew detector, and wherein the enable input signal is only active during the first operating mode.
