這些參數(shù)包括振蕩器環(huán)路的頻率精度、晶體看到的驅(qū)動(dòng)電平和振蕩器的閉環(huán)增益裕度。

振蕩器環(huán)路振蕩的頻率應(yīng)盡可能接近晶體的指定載頻。如果在頻域上偏離系統(tǒng)邊界條件太遠(yuǎn)，可能會(huì)導(dǎo)致系統(tǒng)故障或失效。
為了達(dá)到所需的頻率精度，石英晶體必須看到等效于晶體制造時(shí)的電鍍電容設(shè)置的電路電容，如10pF, 12pF, 18pF等。

easuring in-circuit crystal performance eliminates the problem by converting the unknowns into well knowns. Characterizing the complete frequencyselective network including board parasitics minimizes uncertainty and maximizes confidence in long term system reliability. These parameters include frequency accuracy of the oscillator loop, drive level seen by the crystal, and the closed-loop Gain Margin of the oscillator. The frequency at which the oscillator loop is oscillating should be as close as possible to the specified carrier frequency of the crystal. Deviating too far from the system’s boundary condition in frequency domain may result in system fault or failure. To achieve desired frequency accuracy, the crystal must see in-circuit capacitance equivalent to the plating capacitance set when the crystal was manufactured, such as 10pF, 12pF, 18pF, etc. The challenge lies in the fact that most MCU datasheets do not clearly outline the expected values for Cin and Cout; even though they play a critical role in the final oscillation frequency. The current limiting resistor is rarely engaged, since most MCU embedded oscillator loops do not present excessive drive to the crystal.
