5 VECL Voltage Controlled
Oscillator Amplifier
Description
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.
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 510 W. This facilitates
direct ac−coupling of the output signal into a transmission line.
Because of this output configuration, an external pull−down resistor is
not required to provide the output with a dc current path. This output is
intended to drive one ECL load (3.0 pF). If the user needs to fanout the
signal, an ECL buffer such as the EL16 (EL11, EL14) type Line
Receiver/Driver should be used.
