摘要： An ultrawideband (UWB) frequency-tracking method and related device are provided. The method includes the following steps: (a) using an initial frequency seed to automatically track and compensate the clock signal of the USB peripheral device; (b) determining whether the automatic tracking and compensating of the clock signal is successful, for example, within a pre-defined duration; (c) if not successful in step (b), setting a new frequency seed; (d) setting the USB peripheral device off-line; and (e) reconnecting the USB peripheral device and using the new frequency seed to perform the tracking and compensating of the clock signal. The setting off-line step is to disable the pull-up resistor of the D+ signal or the pull-up resistor of the D− signal of the USB peripheral device so that the USB peripheral device becomes off-line.
