5 V ECL Voltage Controlled Oscillator Amplifier

The MC100EL1648 is a voltage controlled oscillator amplifier that requires an external parallel tank circuit consisting of the inductor (L) and capacitor (C). A varactor diode may be incorporated into the tank circuit to provide a voltage variable input for the oscillator (VCO). This device may also be used in many other applications requiring a fixed frequency clock.
