Abstract
An apparatus comprising at least two controllers each providing control information for controlling phase or frequency of a digital signal, a combiner for combining control information from the at least two controllers to combined control information and a phase rotator for adjusting, by using phase rotation, one or more of the phase and the frequency of the digital signal on the basis of the combined control information.
Claims15
An apparatus, comprising:
- a first controller configured to provide first control information to adjust a phase of a digital signal;
- a second controller configured to provide second control information to adjust a frequency of the digital signal;
- a first combiner configured to combine two or more frequency parameters into a combined frequency parameter, and provide the combined frequency parameter to the second controller;
- a second combiner configured to combine the provided control information from the first controller and the second controller into combined control information;
- and
- a phase rotator configured to adjust, by using phase rotation, the phase and the frequency of the digital signal on the basis of the combined control information.
