The ATS037 series from CTS Corporation is a lineup of 3.6864 MHz crystals designed for a wide range of digital and analog applications. These crystals provide a stable reference frequency, which is crucial for synchronization in systems that require precise timing.

If you're working on projects involving microcontrollers, FPGA designs, or any system where accurate timing is essential, these crystals are a go-to choice. They are commonly found in devices such as network equipment, test and measurement instruments, and medical devices where reliable performance is critical.

One thing worth noting is the stability of these crystals. They offer excellent temperature stability, making them ideal for environments where temperature fluctuations might affect the performance of other components. Engineers tend to reach for this when they need a robust, low-jitter reference clock that can handle the rigors of various industrial and commercial applications without compromising on accuracy.
