WebThe drive level is the power dissipated by the crystal unit while operational. The power is a function of the applied current and is usually expressed in terms of milliwatts (mW) or microwatts (µW). Crystal units are specified as having certain maximum values of drive level, which transform as functions of the frequency and mode of operation. WebThe drive level (P) is determined by Formula (3) below. Where I is the current flowing to the crystal unit, and Reis the equivalent resistance when the crystal unit is under load. If …

WebCrystals below 30MHz are often specified at the fundamental frequency; above 30MHz they are typically specified as 3 rd, 5 th, or even 7 th overtone. (Overtones occur only at odd multiples.) Consequently, it is important to know whether the oscillator is operating in fundamental or overtone mode.
