Typical application for Pierce oscillator
The low-profile CX miniature leaded crystal is ideal for small,
high density, battery operated portable products. A CX crystal
incorporated into a Pierce oscillator (single inverter) circuit
provides a high stability with low current consumption. A
conventional HCMOS Pierce oscillator circuit is shown below. The
crystal is effectively inductive and in a Pi-network circuit with C
and C providing the additional phase shift necessary to sustain
oscillation. The oscillation frequency (f ) is 15 to 150ppm above
the crystals series resonant frequency (f ).
R is used to limit the crystals drive level by forming a voltage
divider between R and C . R also stabilizes the oscillator against
changes in the amplifiers output resistance (R ). R should be
increased for higher voltage operation.
The CX crystal calibration tolerance is influenced by the effective
circuit capacitances, specified as the load capacitance (C ).
C is approximately equal to:

Typical Application
NOTE: C and C include stray layout capacitance to ground. C is
the stray shunt capacitance between the crystal terminals. In
practice, the effective valus of C will be less than that calculated
from C , C , and CS values due to the effect of the amplifier output
resistance. C should be minimized.
The oscillation frequency (f ) is approximately equal to:
