Voltage Controlled Oscillator

The MC1648 requires an external parallel tank circuit consisting of the nductor L and capacitor C . For Maximum Performance QL & 8805 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 . The MC1648 was designed for use in the Motorola Phase& 8211 Locked Loop shown in Figure 9.

This device may also be used in many other applications requiring a fixed or variable frequency clock source of high spectral purity.

The MC1648 may be operated from a 5.0Vdc supply or a & 8211 5.2Vdc supply, depending upon system requirements.
