PLL Frequency Synthesizer with Serial Interface

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 interruption
