APPLICATION INFORMATION
Figure 3 shows a typical application of the SN74LVC1GX04 in a Pierce oscillator circuit. The buffered inverter
(SN74LVC1G04 portion) produces a rail-to-rail voltage waveform. The recommended load for the crystal shown
in this example is 16 pF. The value of the recommended load (CL) can be found in the crystal manufacturer's
data sheet.
Values of C1 and C2 are chosen so that and C1 ≡ C2. Rs is the current-limiting resistor, and the
value depends on the maximum power dissipation of the crystal. Generally, the recommended value of Rs is
specified in the crystal manufacturer's data sheet and, usually, this value is approximately equal to the reactance
of C2 at resonance frequency, i.e., . RF is the feedback resistor that is used to bias the inverter in the
linear region of operation. Usually, the value is chosen to be within 1 MΩ to 10 MΩ.

APPLICATION INFORMATION
Testing
After the selection of proper component values, the oscillator circuit should be tested using these components.
To ensure that the oscillator circuit performs within the recommended operating conditions, follow these steps:
1. Without a crystal, the oscillator circuit should not oscillate. To check this, the crystal can be replaced by its
equivalent parallel-resonant resistance.
2. When the power-supply voltage drops, the closed-loop gain of the oscillator circuit reduces. Ensure that the
circuit oscillates at the appropriate frequency at the lowest VCC and highest VCC.
3. Ensure that the duty cycle, start-up time, and frequency drift over time is within the system requirements.
