... GHz PLL Frequency Synthesizer Includes On–Board 64/65 Prescaler The MC145201 is a single–package synthesizer with serial interface capable of direct usage up to 2.0 GHz. A special architecture makes this PLL very easy to program because a byte–oriented format is utilized. Due to the patented BitGrabber registers, no address/steering bits are required for random access of the three registers. Thus, tuning can be accomplished via a 3– ...
