SM5170AV NIPPON PRECISION CIRCUITS INC. PLL Synthesizer IC OVERVIEW The SM5170AV is a PLL synthesizer IC developed for application in pagers. It incorporates independently-controlled reference frequency and FIN input frequency dividers, and operates from a low-voltage supply to realize low power dissipation. It features a charge pump that operates at 3 V, making possible a wide range of VCO designs. FEATURES s s Supply voltages • VDD1 = 0.95 to 1.2 V (prescaler, counters) • VDD2 = 2.0 to 3.3 V (charge pump) FIN input frequency • fFIN = 300 MHz (VDD1 = 0.95 V) • fFIN = 330 MHz (VDD1 = 1.0 V) s s s s s Reference frequency • fXIN = 25 MHz (VDD1 = 0.
