PLL Frequency Synthesizer with Serial Interface

MC145170-2 / MLE145170-P2 / ML145170 / MLE145170-EP PLL IC Chip.

The new MC145170-2 is pin-for-pin compatible with the MC145170-1.  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 BitGrabberTM 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 MLE145170-P2 that we have is the military version of this PLL which is a higher quality chip.

We have several thousand of these IC chips in stock. Call for more information and/or quantity pricing.
