Low-Voltage 1.1 GHz PLL Frequency Synthesizer
Includes On–Board 64/65 Prescaler

The MC145192 is a low–voltage single–package synthesizer with serial interface capable of direct usage up to 1.1 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–byte serial transfer to the 24–bit A register. The interface is both SPI and MICROWIRE™ compatible.

The double–buffered R register allows new divide ratios to be presented to the three counters (R, A, and N) simultaneously.
