这些参数包括振荡器环路的频率精度、晶体看到的驱动电平和振荡器的闭环增益裕度。

振荡器环路振荡的频率应尽可能接近晶体的指定载频。如果在频域上偏离系统边界条件太远,可能会导致系统故障或失效。
为了达到所需的频率精度,石英晶体必须看到等效于晶体制造时的电镀电容设置的电路电容,如10pF, 12pF, 18pF等。

挑战在于大多数MCU数据表没有清楚地列出Cin和Cout的期望值;尽管它们在最终振荡频率中起着关键作用。限流电阻很少被使用,因为大多数MCU嵌入式振荡器回路不会对晶体产生过多的驱动。

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.
