MC100EL1648DG

The MC100EL1648DG is a voltage-controlled Oscillator Amplifier requires an external parallel tank circuit consisting of the inductor and capacitor. 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. The MC100EL1648 is ideal in applications requiring a local oscillator, systems that include electronic test equipment and digital high-speed telecommunications. The MC100EL1648 is based on the VCO circuit topology of the MC1648. The MC100EL1648 uses advanced bipolar process technology which results in a design which can operate at an extended frequency range. The ECL output circuitry of the MC100EL1648 is not a traditional open emitter output structure and instead has an on-chip termination emitter resistor, RE, with a nominal value of 510Ω. This facilitates direct ac-coupling of the output signal into a transmission line.
