Abstract
Adjustment of the output frequency of a frequency synthesizer can be optimized in the following manner. Once a frequency adjustment request is detected, which indicates a selected frequency, a frequency difference is calculated between the selected frequency and the present frequency. A frequency scaling factor is then determined. Once the frequency difference and the frequency scaling factor are determined, a frequency adjustment time is calculated based on a proportional relationship between the frequency difference and the frequency scaling factor. The bandwidth of a multi-bandwidth filter is adjusted to a second bandwidth for the duration of the calculated frequency adjustment time. The output frequency of the frequency synthesizer is adjusted from the present frequency to the selected frequency prior to the expiration of the frequency adjustment time. Upon expiration of the frequency adjustment time, the bandwidth of the multi-bandwidth filter is adjusted from the second bandwidth to the first bandwidth.
