Crystal drive level
WebOct 2, 2015 · Drive level can be determined through simulation of the oscillator with the maximum expected value of R1 used in the crystal model. If a realistic model of the behaviour of the active section of the oscillator is not available then the current in the crystal should be measured using a high bandwidth current probe. WebMar 1, 2006 · The paper describes an experimental set-up allowing resonator's motional parameter measurements with variable drive level as low as - 100 dBm in a controlled temperature enclosure.

WebPlugging it into the formula. DL=Rm× (2πf (CL+C0))^2×Vrms^2. And checking if it is within spec of the crystal and adding a series resistor if necessary. However, how can one find certainty that the IC will still properly function. What is the correct interpretation of the drive level on the IC datasheet. (Crystal datasheet is quite obvious) 2. 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.
