What is the minimum information needed to specify a crystal? 对无源晶振正确报价需要的最基本信息有哪些？

The following specifications are required to be able to quote the correct part:

Frequency of oscillation振荡频率: (MHz)

Model Name or Package size型号名称或尺寸: (mm)

How many connections (pads) 焊盘数量:4 or 2

Tolerance: (±ppm).调整频差

The maximum acceptable deviation from the required frequency of oscillation, when at 25°C.
在25°C时，可接受的振荡频率偏差

Stability频率稳定度: (±ppm)

The maximum frequency deviation across the temperature range, referenced to the frequency at 25°C (Tolerance).

以25°C频率为参考，温度范围内的频率偏差（容差）

Temperature Range工作温度范围: (°C)

The temperature range over which the stability will be within specification.

稳定性在规范范围内的温度范围

Load Capacitance负载电容: (pF)

The combined capacitance presented to the crystal by the PCB. Including any stray capacitance.
PCB向晶体呈现的总电容，包括任何杂散电容

For MHz frequencies

Overtone Order: The number of physical oscillations within the quartz. In most cases, this will be fundamental.

MHz晶体振荡模式：基频还是泛音？在大多数情况下，为基频振荡模式。
