Oscillators are electronic components that generate electrical signals that are used in communications, instrumentation and other applications. Oscillators are often used to create alternating current (AC) electrical signals. Oscillators are typically used in applications that require precise frequency control. The ECS-3225S18-440-FN-TR oscillator is a temperature-compensated crystal oscillator (TCXO) designed to provide temperature-stable frequency control in a variety of applications.

The ECS-3225S18-440-FN-TR is a low cost, high performance TCXO that operates over a frequency range from 4.0 MHz to 120.0 MHz. The ECS-3225S18-440-FN-TR is frequently used in a variety of communications applications such as cellular base stations, mobile telephone systems and satellite applications, as well as in instrumentation applications such as metering and medical instrumentation. The ECS-3225S18-440-FN-TR offers frequency stability suitable for many of these applications.

The ECS-3225S18-440-FN-TR operates using a quartz crystal as its resonator. Quartz crystal oscillators provide very stable frequency characteristics and are considered the most accurate oscillators available today. Quartz crystals are sensitive to temperature, however, and temperature-compensated crystal oscillators (TCXO) are often used to minimize frequency errors due to temperature variations. The ECS-3225S18-440-FN-TR offers temperature compensation in an economical package and is suitable for many applications where high frequency stability is required.

The ECS-3225S18-440-FN-TR is a direct-digital controlled oscillator (DCO) designed to provide optimal frequency control over temperatures ranging from -40°C to +85°C. The oscillator features a programmable frequency tuning range of up to ±30 ppm over its full temperature range. This is accomplished through a direct digital loop coupled with a thermistor to sense temperature and an integrated temperature compensation network designed to compensate the oscillator\'s frequency over temperature. This combination of components allows the ECS-3225S18-440-FN-TR to provide high performance frequency stability over temperatures ranging from -40°C to +85°C.

The ECS-3225S18-440-FN-TR also offers high performance phase noise characteristics. The phase noise is typically -154 dBc/Hz at a 1-kHz offset and -165 dBc/Hz at a 10-kHz offset; both figures are measured at a frequency of 7.8 MHz. This level of phase noise performance makes the ECS-3225S18-440-FN-TR suitable for applications where signal integrity is a concern, such as in cellular base stations and satellite uplink systems.

The ECS-3225S18-440-FN-TR oscillator is a highly versatile device offering low power consumption and reliable temperature-stable performance. Its small size, low cost and high efficiency make it a suitable choice for a wide variety of applications and applications requiring precision frequency control.
