高可靠性能的石英晶体谐振器是调制解调器的理想选择ABM8-16.000MHZ-7-1-U-T，有两种方法来为系统计时:使用一个完全集成的晶体振荡器，或配合SMD晶振直接用片上振荡器。使用XO往往会增加功耗和系统成本。通过将石英晶体与单片机内部的嵌入式皮尔斯振荡器电路配合使用，降低了系统功耗和成本。大多数嵌入式振荡器电路使用皮尔斯振荡器，这是一种配置，包括一个简单的逆变放大器作为回路内的逆变增益元件。
在大多数情况下，放大器单元是在MCU内部，而频率选择网络是在MCU外部。外部网络的关键部件是石英晶体。还使用了相关的回路电容和串联(限流)电阻(Rs)。

There are two ways to clock a system: use a fully integrated crystal oscillator, or mate the crystal directly with the on-chip oscillator. Using an XO tends to increase power consumption and system costs. By mating a quartz crystal with the embedded Pierce oscillator circuit inside the MCU, system power consumption and costs are reduced. The majority of embedded oscillator circuits use the Pierce oscillator, a configuration which comprises of a simple inverter amplifier as the inverting gain element within the loop.

In most cases, the amplifier unit is internal to the MCU and the frequency-selective network is external to the MCU. The key component in the external network is the quartz crystal. Associated loop capacitors and a series (current limiting) resistor (Rs) are also used.
Quartz Crystals used in this approach are coined as Parallel Plated Crystals, with standard values such as 10pF, 12pF, 18pF, etc. This implies that the final oscillation frequency will be within the tolerance of the standalone quartz crystal when the closed-loop effective capacitance is exactly equal to the quartz plating capacitance.
