In an embodiment, a circuit device includes a first counter responsive to a clock signal and to a first control word having a first precision. The counter produces a first control signal related to the first control word at a first output. The circuit device further includes a second counter responsive to the clock signal and to a second control word having the first precision. The second counter produces a second control signal related to the second control word at a second output. The circuit device also includes a filtering circuit responsive to the first output and the second output to receive the first and second control words. The filtering circuit is adapted to produce an output control signal related to the first and second control words, where the output control signal has a second precision that is greater than the first precision.
