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.
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
linear region of operation. Usually, the value is chosen to be within 1 M
to 10 M.
