The ECS-36-S crystal series from ECS Inc. International is a lineup of 3.6864 MHz quartz crystals designed specifically for microprocessor timing applications. These crystals are commonly used in systems requiring precise clocking, such as embedded systems, industrial control units, and test equipment.

If you're working on any project that demands high accuracy and stability in timing, these crystals are a go-to choice. One thing worth noting is their reliability—they provide consistent performance over a wide range of temperatures, which is crucial in many real-world applications. Engineers tend to reach for this when they need a reliable source for the NTSC video standard or other digital communication protocols that rely on precise timing.

Another practical application is in GPS modules, where the 3.6864 MHz frequency is often used as a reference for generating sub-harmonics. The crystals in this series are known for their excellent phase noise characteristics, making them ideal for maintaining accurate time synchronization in such systems.

Overall, the ECS-36-S crystals offer a solid solution for timing applications where precision and stability are paramount. Their robust design ensures long-term performance, making them a trusted component in many electronic systems.
