Either a pre-packaged oscillator or a simple oscillator
circuit with TTL gates can be used as an external
crystal oscillator circuit. Pre-packaged oscillators
provide a wide operating range and better stability. A
well designed crystal oscillator will provide good perfor-
mance with TTL gates. Two types of crystal oscillator
circuits can be used: one with parallel resonance or one
with series resonance.
Figure 4-3 shows an implementation example of a
parallel resonant oscillator circuit. The circuit is
designed to use the fundamental frequency of the
crystal. The 74AS04 inverter performs the 180° phase
shift that a parallel oscillator requires. The 4.7 kΩ
resistor provides the negative feedback for stability.
The 10 kΩ potentiometers bias the 74AS04 in the
linear region. This circuit could be used for external
oscillator designs.
FIGURE 4-3:
Figure 4-4 shows a series resonant oscillator circuit.
This circuit is also designed to use the fundamental
frequency of the crystal. The inverters perform a 360°
phase shift in a series resonant oscillator circuit. The
330 kΩ resistors provide the negative feedback to bias
the inverters in their linear region.

For applications where precise timing is not a require-
ment, the RC oscillator option is available. The
operation and functionality of the RC oscillator is
dependent upon a number of variables. The RC
oscillator frequency is a function of:
• Supply voltage
• Resistor (R
• Operating temperature.
The oscillator frequency will vary from unit to unit due
to normal process parameter variation. The difference
in lead frame capacitance between package types will
also affect the oscillation frequency, especially for low
C
tolerance of the external R and C components.
Figure 4-5 shows how the R/C combination is
connected.
The oscillator frequency, divided by 4, is available on
the OSC2/CLKOUT pin and can be used for test
purposes or to synchronize other logic.
