Televisions, especially HDTV, require tremendous bandwidth, however a time interval to switch communication channels may result in the loss of several image frames or a large portion of a single image frame. Unfortunately, small glitches in television signals are not tolerable since this affects the quality of the entertainment. Thus, wireless television tuners are unacceptable to most users because of frequency of glitches occurring as a result of channel hopping. A novel wireless television tuner system is thus disclosed that switches—hops—between frequency channels for transmitting television data to the wireless television tuner. The novel tuner uses a fractional-N (FRAC-N) synthesizer with an improved settling time in order to reduce potential glitches occurring as a result of the channel hopping.
