    Product Description
    QUARTS CRYSTAL CHARACTERISTICS
    CRYSTAL EQUIVALENT CIRCUIT
    The equivalent circuit of a quartz crystal is shown to explain the basic elements governing the crystal characteristics and performance. It consists of a motional capacitance Cl, inductance Ll, series resistance Rl, and a shunted capacitance C0. The first three parameters are known as the “motional parameters” of the quartz crystal element. See Fig. 2.
    SERIES RESONANCE When a crystal is operating at series resonance (Fs), it looks resistive in the circuit. Thus, impedance at Fs is near zero. In a well designed series resonant circuit, correlation is not a problem and load capacitance does not have to be specified. See Fig. 3.
