WAVEFORM CONDITIONING SINE OR SQUARE WAVE
The peaktopeak swing of the tank circuit is set
internally by the AGC pin. Since the voltage swing of the
tank circuit provides the drive for the output buffer, the AGC
potential directly affects the output waveform. If it is desired
to have a sine wave at the output of the MC100EL1648, a
series resistor is tied from the AGC point to the most
negative power potential (ground if positive volt supply is
used, 5.2 V if a negative supply is used) as shown in
Figure 13. At frequencies above 100 MHz typical, it may be
desirable to increase the tank circuit peaktopeak voltage
in order to shape the signal into a more square waveform at
the output of the MC100EL1648. This is accomplished by
tying a series resistor (1.0 k
W minimum) from the AGC to
the most positive power potential (+5.0 V if a positive volt
supply is used, ground if a 5.2 V supply is used). Figure 14
illustrates this principle.
