Oscillators

An oscillator is an electronic circuit that produces alternating current or voltage of a certain frequency, amplitude, and waveform. The 637E15365I3T oscillator is a type of versatile IC oscillator that combines a temperature-compensated crystal oscillator (TCXO) with a voltage-controlled temperature-compensated crystal oscillator (VCTCXO) and offers superior performance over a wide temperature range of −40°C to +85°C. It is widely used in high-precision frequency control applications, such as telecommunications systems, navigation systems, radar systems, and electronic meters, among others.

Application Field and Working Principle

The 637E15365I3T oscillator has a wide range of applications, primarily in precision frequency control. It is used in telecommunication systems, navigation systems, radar systems, and electronic meters. As the building blocks of communication systems, oscillators provide a high-precision reference frequency to facilitate stable and accurate communication. Carrier frequencies are generated using oscillators, allowing wireless signals to be transmitted over long distance, making them a critical element of any communication system.

The 637E15365I3T oscillator is composed of the XtalCORE oscillator and the LO prescaler. XtalCORE is a temperature-compensated crystal oscillator (TCXO) which combines a high-performance quartz crystal resonator with an advanced temperature tracking circuit. It ensures the oscillator output is stable and precise, regardless of the environmental temperature fluctuations.

The LO prescaler is a voltage-controlled temperature-compensated crystal oscillator (VCTCXO). It is designed to use a wide range of voltage inputs to provide the required output frequency. This provides engineers with great flexibility in terms of system design, as they can choose the best parameters for their specific application. In addition, the LO prescaler incorporates a low-noise amplifier and a frequency divider, allowing the output frequency to be tuned accurately and without introducing any additional noise.

The 637E15365I3T oscillator also offers exceptional operating stability over a wide temperature range of -40°C to +85°C. This makes it ideal for applications that require long-term performance in extreme environments.

In summary, the 637E15365I3T oscillator is a versatile IC oscillator that combines a temperature-compensated crystal oscillator (TCXO) with a voltage-controlled temperature-compensated crystal oscillator (VCTCXO) and offers superior performance over a wide temperature range of −40°C to +85°C. It is widely used in high-precision frequency control applications such as telecommunications systems, navigation systems, radar systems, and electronic meters.
