Voltage Controlled Oscillator
The MC12148 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 MC12148 is ideal in applications requiring a local oscillator. Systems
include electronic test equipment and digital high–speed
telecommunications.
The MC12148 is based on the VCO circuit topology of the MC1648. The
MC12148 has been realized utilizing Motorola’s MOSAIC III advanced
bipolar process technology which results in a design which can operate at a
much higher frequency than the MC1648 while utilizing half the current.
Please consult with the MC1648 data sheet for additional background
information.
The ECL output circuitry of the MC12148 is not a traditional open emitter
output structure and instead has an on–chip termination resistor with a
nominal value of 500 ohms. 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. If the user
needs to fanout the signal, an ECL buffer such as the MC10EL16 Line
Receiver/Driver should be used.
NOTE: The MC12148 is NOT useable as a crystal oscillator.
