ECS-122.8-S-7SX-TR Crystals, Oscillators, Resonators

Crystals are solid state components, often quartz or ceramic, that can oscillate at particular frequencies, thereby regulating the timing and rate of the electrons passing through them. The ECS-122.8-S-7SX-TR crystal is a popular choice for applications that require a timing reference in an electronic circuit. The crystal oscillator is a type of solid state device, meaning it does not require any moving parts in the system, unlike mechanical oscillators.

The ECS-122.8-S-7SX-TR is commonly used in today’s high-performance circuit designs thanks to its small size and high frequency stability. It is a low-temperature-coefficient quartz crystal, along with a nine-stage monolithic CMOS oscillator–combined to form a temperature-compensated oscillator (TCXO).

The higher quality crystals, such as the ECS-122.8-S-7SX-TR, are known for their excellent selectivity characteristics, even with the added temperature compensation, meaning they can reach even higher frequencies with extreme precision and accuracy. The ECS-122.8-S-7SX-TR has an oscillator frequency of 122.8 MHz, a deviation of ± 10 ppm, and a temperature coefficient of ± 5 ppm.

The working principle of the ECS-122.8-S-7SX-TR is relatively simple. The crystal acts like a tiny resonator, vibrating at the frequency specified by its design. This vibration is then picked up by the electronic circuit, providing it with the necessary timing reference. This allows the circuit to accurately measure time and synchronize electrical signals, ultimately improving its overall performance.

The ECS-122.8-S-7SX-TR is most typically used in a crystal-controlled oscillator (or XO), providing timing signals to various parts of a circuit. Quartz crystals are preferred in XOs due to their extreme precision and accuracy compared to alternatives such as clock oscillators. The ECS-122.8-S-7SX-TR is often used in RF applications such as Wi-Fi, cellular radios, WiFi routers, etc. due to its wide operating temperature range and low phase noise.

In addition to its applications in RF systems, the ECS-122.8-S-7SX-TR is commonly found in microcontroller systems. Its stability and small size make it an ideal choice for embedded systems that require accurate and reliable timing signals. Other applications include digital-to-analog converters, frequency meters, and audio systems.

The ECS-122.8-S-7SX-TR crystal is an essential component for modern electronic systems. Its small size, high frequency stability and temperature compensation features make it a largely preferred choice for a wide range of applications. As the need for precision and accuracy grows, so does the popularity of the ECS-122.8-S-7SX-TR crystal.
