MC100EL1648
5 VECL 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.
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 . 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.
NOTE: The MC100EL1648 is NOT useable as a crystal oscillator.

OPERATION THEORY
Q2 and Q3, in conjunction with output transistor Q1,
provide a highly buffered output that produces a square
wave. The typical output waveform can be seen in Figure 4.
The bias drive for the oscillator and output buffer is provided
by Q9 and Q11 transistors. In order to minimize current, the
output circuit is realized as an emitter−follower buffer with
an on chip pull−down resistor RE.
Figure 5 illustrates the simplified circuit schematic for the
MC100EL1648. The oscillator incorporates positive feedback
by coupling the base of transistor Q6 to the collector of Q7. An
automatic gain control (AGC) is incorporated to limit the
current through the emitter−coupled pair of transistors (Q7 and
Q6) and allow optimum frequency response of the oscillator.
In order to maintain the high quality factor (Q) on the oscillator,
and provide high spectral purity at the output, transistor Q4 is
used to translate the oscillator signal to the output differential
pair Q2 and Q3. Figure 16 indicates the high spectral purity
of the oscillator output (pin 4 on 8−pin SOIC). Transistors

FIXED FREQUENCY MODE
Only high quality surface−mount RF chip capacitors
should be used in the tank circuit at high frequencies. These
capacitors should have very low dielectric loss (high−Q). At
a minimum, the capacitors selected should be operating at
100 MHz below their series resonance point. As the desired
frequency of operation increases, the values of the tank
capacitor will decrease since the series resonance point is a
function of the capacitance value. Typically, the inductor is
realized as a surface−mount chip or a wound coil. In
addition, the lead inductance and board inductance and
capacitance also have an impact on the final operating point.
The following equation will help to choose the appropriate
values for your tank circuit design.
The MC100EL1648 external tank circuit components are
used to determine the desired frequency of operation as
shown in Figure 8, tank option #2. The tank circuit
components have direct impact on the tuning sensitivity, IEE,
and phase noise performance. Fixed frequency of the tank
circuit is usually realized by an inductor and capacitor (LC
network) that contains a high Quality factor (Q). The plotted
curve indicates various fixed frequencies obtained with a
single inductor and variable capacitor. The Q of the
components in the tank circuit has a direct impact on the
resulting phase noise of the oscillator. In general, when the
Q is high the oscillator will result in lower phase noise.

to choose desired value of inductor/capacitor component for
the wanted frequency. The lead inductance and board
inductance and capacitance will also have an impact on the
tank component values (inductor and capacitor).

VOLTAGE CONTROLLED MODE
The tank circuit configuration presented in Figure 11,
Voltage Controlled Varactor Mode, allows the VCO to be
tuned across the full operating voltage of the power supply.
Deriving from Figure 6, the tank capacitor, C, is replaced
with a varactor diode whose capacitance changes with the
voltage applied, thus changing the resonant frequency at
which the VCO tank operates as shown in Figure 3, tank
option #1. The capacitive component in Equation 1 also
needs to include the input capacitance of the device and
other circuit and parasitic elements.
When operating the oscillator in the voltage controlled
mode with Tank Circuit #1 (Figure 3), it should be noted that
the cathode of the varactor diode (D), pin 8 (for 8 lead
package) or pin 10 (for 14 lead package) should be biased at
least 1.4 V above VEE.
Typical transfer characteristics employing the
capacitance of the varactor diode (plus the input capacitance
of the device, about 6.0 pF typical) in the voltage controlled
mode is shown in Plot 1, Dual Varactor MMBV609 Vin vs.
Frequency. Figure 6, Figure 7, and Figure 8 show the
accuracy of the measured frequency with the different
variable capacitance values. The 1.0 k resistor in Figure 11
is used to protect the varactor diode during testing. It is not
necessary as long as the dc input voltage does not cause the
diode to become forward biased. The tuning range of the
oscillator in the voltage controlled mode may be calculated
as follows:

Good RF and low−frequency bypassing is necessary on
the device power supply pins. Capacitors on the AGC pin
and the input varactor trace should be used to bypass the
AGC point and the VCO input (varactor diode),
guaranteeing only dc levels at these points. For output
frequency operation between 1.0 MHz and 50 MHz, a 0.1 F
capacitor is sufficient. At higher frequencies, smaller values
of capacitance should be used; at lower frequencies, larger
values of capacitance. At high frequencies, the value of
bypass capacitors depends directly on the physical layout of
the system. All bypassing should be as close to the package
pins as possible to minimize unwanted lead inductance.
Several different capacitors may be needed to bypass
various frequencies.

WAVE−FORM CONDITIONING − SINE OR SQUARE WAVE
Figure 13. At frequencies above 100 MHz typical, it may be
desirable to increase the tank circuit peak−to−peak 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 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.
The peak−to−peak 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
