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.

ORDERING INFORMATION  
The device features fully programmable R and N counters, an amplifier at the  
f
pin, on–chip support of an external crystal, a programmable reference

output, and both single– and double–ended phase detectors with linear transfer  
functions (no dead zones). A configuration (C) register allows the part to be  
configured to meet various applications. A patented feature allows the C  
register to shut off unused outputs, thereby minimizing noise and interference.  
In order to reduce lock times and prevent erroneous data from being loaded  
into the counters, a patented jam–load feature is included. Whenever a new  
divide ratio is loaded into the N register, both the N and R counters are  
jam–loaded with their respective values and begin counting down together. The  
phase detectors are also initialized during the jam load.
