Advance Information
PLL Frequency Synthesizer with Serial Interface CMOS
The new MC145170–1 is pin–for–pin compatible with the MC145170. A comparison of the two parts is shown in the table below. The MC145170–1 is recommended for new designs. The MC145170–1 is a single–chip synthesizer capable of direct usage in the MF, HF, and VHF bands. A special architecture makes this PLL the easiest to program in the industry. Either a bit– or byte–oriented format may be used. 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 2–byte serial transfer to the 16–bit N register.
