Equivalent Series Resistance of the Crystal 晶体的等效电阻

Equivalent Series Resistance of the Crystal 晶体的等效电阻

英文解释:

The equivalent series resistance of the crystal must be within the specifications so that the crystal can have a reliable vibration.

中文解释:

晶体谐振器(无源晶振)的等效串联电阻(ESR)必须在指定规格范围内。如果串联电阻过大,晶体谐振器可能无法正常起振或稳定输出频率。

Equivalent Series Resistance of the Crystal 晶体的等效电阻

(Equivalent Resistance of the Crystal SMD3226 26MHz )

通常情况下,我们希望晶振的ESR越小越好。晶振ESR越小,意味着晶振越容易起振,且电流功耗越小。表格中芯片对晶体SMD3225 26MHz等效串联电阻(ESR)的要求是≤60Ω。

Frequency tolerance则指的是晶振26MHz的调整频差,该电气参数为晶振频率精度指标之一。
