Abstract
A control method utilized in a clock data recovery device supporting a plurality of frequency bands, for controlling the clock data recovery device to select an operating frequency band from the plurality of frequency bands and to generate a recovery clock for generating retimed data, includes receiving a serial data stream with a data frequency; making each frequency band of the plurality of frequency bands correspond to a plurality of frequency band groups, wherein each frequency band group includes at least one frequency band and corresponds to different frequency ranges; selecting a frequency band group from the plurality of frequency band groups as a coarse-tuned frequency band group according to the data frequency and a locking voltage range; and selecting a frequency band from the plurality of frequency bands according to the data frequency, the locking voltage range and the coarse-tuned frequency band group for generating the recovery clock.
