Crystals play an important role in the workings of modern technology, achieving multiple communication and synchronization functions that simply can’t be accomplished with other means. The ECS-40-20-7S-TR, in particular, is a top-of-the-line, fully automated crystal oscillator designed for the industry leader known as Eurochron. This technical marvel is well suited for applications that require accurate and reliable zero drift timing control.First, the ECS-40-20-7S-TR utilizes a special packaging that drastically reduces the time needed from start-up to full operation in the widest range of conditions and applications. This makes it ideal for environments that require the utmost precision and highest level of performance. It boasts the tightest frequency stability ever achieved in a temperature cycle and even after thermal shock, with a mean-time-between-failure rate of greater than 100,000 hours. It’s also capable of operating at temperatures that range as low as -40 degrees Celsius and up to as high as 80 degrees Celsius.The ECS-40-20-7S-TR’s crystal-driven oscillator circuit boasts two features that combine to deliver unparalleled performance. The first is SXO, a combination of a low cost crystal oscillator, a low phase noise clock generator, and a frequency reference. The second is a proprietary combination of temperature compensated crystal and piezoelectric technology, providing a very low phase noise and excellent frequency stability over temperature.The ECS-40-20-7S-TR’s frequency options are inherently stable up to several hundred millihertz (kHz). This frequency accuracy and precision is maintained over temperature and aging, even during the most extreme conditions. Its maximum frequency stability available is a staggering 250 parts-per-billion (ppb).The device also offers a range of quality factors to meet various cost and performance criteria. Its extremely low capture time (
