Crystal oscillators are celebrated in many applications which demand highly precise, reliable timing reference. The ECS-270-20-5G3XDS-F-TR is one of the most precise and reliable crystals in the industry. As stated by its manufacturer, ECS Inc, the ECS-270-20-5G3XDS-F-TR is a “high do-it-all oscillator.” The ECS-270-20-5G3XDS-F-TR is ideally suited for applications requiring a precise and accurate timing reference with a frequency range of 20 MHz to 270 MHz. It features a frequency stability of ±2.5 ppm over the entire temperature range of -10°C to +85°C and a low phase noise at the oscillator output. It also has a maximum supply voltage of 5V, a low power consumption of only 8mA, and a maximum storage temperature range of -40°C to +85°C. The ECS-270-20-5G3XDS-F-TR is the perfect choice for applications such as high speed data communication, timing-critical or temperature sensitive microprocessor operation, and precision analog and digital measurement. It is also suitable for radar and avionics systems, point-to-point networking, industrial control systems, base stations, switched digital services, telecommunications, cellular telephony, VOIP systems, and satellite communication systems. The working principle behind the ECS-270-20-5G3XDS-F-TR is simple yet highly effective. The crystal oscillator takes advantage of the mechanical vibrations produced by a quartz crystal to create the oscillations necessary for timing reference in a circuit. The quartz crystal is housed in a sealed case and is securely attached to two metal electrodes. The crystal vibrates at its resonant frequency when an electric current passes through it, and induces a voltage at the electrodes. The oscillation frequency can be adjusted by changing the capacitance of the crystal, this is accomplished by adding a capacitor to the circuit. The ECS-270-20-5G3XDS-F-TR crystal is a superior oscillator and its superior performance is largely due to its robust design and a low phase noise clock signal provided by its Tunable Sub-Harmonic Symmetric Oscillator (TSOS) technology. This TSOS technology eliminates the need for external filtering components, resulting in a significantly improved signal-to-noise ratio for the signal produced. The ECS-270-20-5G3XDS-F-TR crystal is an ideal choice for a wide range of applications requiring a highly precise timing reference. Its superior performance is largely attributed to its robust design, low power consumption, and the introduction of the TSOS technology. It is the perfect choice for applications such as high speed data communication, timing-critical or temperature sensitive microprocessor operation, and precision analog and digital measurement.
