comparison of the two parts is shown in the table below. The MC145170–1 is

recommended for new designs.

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.

f in 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

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.
