1 Introduction

The new MC145170-2 is pin-for-pin compatible with the MC145170-1. A comparison of the

two parts is shown in the table below. The MC145170-2 is recommended for new designs

and has a more robust power-on reset (POR) circuit that is more responsive to momentary

power supply interruptions. The two devices are actually the same chip with mask options for

the POR circuit. The more robust POR circuit draws approximately 20

µA

additional supply

current. Note that the maximum specification of 100

µA

quiescent supply current has not

changed.

The MC145170-2 is a single-chip synthesizer capable of direct usage in the MF, HF, and

VHF bands. A special architecture makes this PLL easy to program. 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.

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)

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

counting down together. The phase detectors are also initialized during the jam load.
