Suntsu石英晶体优化电路板性能

Suntsu石英晶体优化电路板性能，Every board design and its characteristics are unique, and for your board to perform at its best, specifications, like crystal specifications, must be appropriately tuned. Most crystal manufacturers have standard parts known to perform well, but that doesn’t always mean those parts will provide optimal performance for your board.

每块电路板的设计及其特性都是独一无二的，为了让您的电路板发挥最佳性能，必须对规格(如晶振规格)进行适当调整。大多数晶振制造商都有性能良好的标准器件，但这并不总是意味着这些器件能为您的主板提供最佳性能。

At Suntsu, we offer our customers a service that not many other manufacturers like us do: crystal circuit analysis. We provide this free analysis because it helps determine the best parameters for your board design and is critical to achieving optimal performance. Keep reading below to understand the importance of our crystal circuit analysis.

Oscillators and the Pierce Circuit Design

While there are various types of oscillators, each with its unique characteristics and features, the most common is the crystal oscillator which uses a piezoelectric crystal as a frequency-selective element. What makes crystal oscillators so popular is their ability to maintain frequency stability for long durations and that they are not as affected by temperature drift.

Most designers are used to working with the Pierce circuit, but that doesn’t necessarily mean they fully understand how it works or how to design it for optimum performance. This circuit requires external load capacitors or internal built-in capacitors along with the crystal and resistor(s) to decide the characteristics of the circuit oscillation. Parameters like frequency output, oscillation gain, negative resistance, and drive level will all be affected if not tuned correctly making it even more important to properly match the crystal used in the circuit with the on-board Pierce oscillator.

大多数设计人员习惯于使用皮尔斯电路，但这并不意味着他们完全了解其工作原理，或者如何设计出最佳性能。该电路需要外部负载电容或内部内置电容以及晶体和电阻来决定电路振荡的特性。如果调谐不正确，频率输出、振荡增益、负电阻和驱动电平等参数都会受到影响，因此将电路中使用的晶体与片上Pierce振荡器正确匹配就变得更加重要。

For Engineers, it’s common to leave the crystal as is and follow the reference design or use off-the-shelf crystal recommendations from crystal manufacturers. Choosing either of these options is fine, and the circuit will generally perform, but it’s possible it may not operate at the optimal performance level. Think of it like a guitar. You can play the guitar whether it’s tuned or not, but the notes never sound their best until the guitar is properly tuned.

Suntsu’s Crystal Circuit Analysis

To help customers tune their boards correctly and reach optimal performance, Suntsu offers something that not many other crystal manufacturers do: crystal circuit analysis. It’s possible to use trial and error to optimize the circuit, but doing this takes time and testing. The easiest way to achieve this is by sending your board to us!
