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: 1 2 0 S A A1 A 0A L L Drive Level Load Capacitance 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: 12 S L 12 S 0 Where F = Series resonant frequency of the crystal C = Motional Capacitance C = Shunt Capacitance S 1 0 f = C1 0 fS 2(C+ C) 0L 1+ Conventional HCMOS Pierce Oscillator Circuit CX-2 Buffer Amplifier Osc.
