MC1648 Overview
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Voltage Controlled Oscillator Consider MC12148 for New Designs The MC1648 requires an external parallel tank circuit consisting of the inductor (L) and capacitor (C). For Maximum Performance QL ≥ 100 at Frequency of Operation. A varactor diode may be incorporated into the tank circuit to provide a voltage variable input for the oscillator (VCO).
