Oscillators are broadly defined as electrical circuits, which generate an output signal with a repeating or oscillating waveform. The TD-14.31818MCE-T oscillator is a high-speed, mid frequency CMOS temperature compensated crystal oscillator (TCXO). The following highlights the application fields and principles of operation.

Applications

The TD-14.31818MCE-T is ideal for many applications that require stability and accuracy in one compact package. It features a frequency stability of ±2 to ±20ppm over a temperature range of -40°C to 85°C and a temperature coefficient of 10ppm/°C to 100ppm/°C over the same temperature range. This makes it suitable for a wide range of applications, including precision timebase and phase-locked loop clock synchronization, switching and data conversion clocks, instrumentation, and mixed signal applications.

Working Principle

The TD-14.31818MCE-T is based on a temperature compensated crystal oscillator (TCXO). A TCXO features a very stable frequency over time and temperature, achieved by using a temperature sensor embedded in an oscillator circuit. The temperature sensor is connected to a voltage controlled oscillator (VCO). The VCO is driven by an external crystal, but its output frequency is modulated by the output of the temperature sensor, and thus stabilized.

The feedback loop is designed to keep the oscillators frequency stable, regardless of temperature. The oscillator circuit includes an amplifier and a voltage regulator, as well as the necessary components to form an oscillator. The amplifier is connected to the oscillator, and the voltage regulator is connected to the temperature sensor and the VCO. When the voltage regulator senses a change in temperature, it adjusts the frequency of the VCO to maintain a constant oscillation frequency.

Conclusion

The TD-14.31818MCE-T oscillator is a high-speed, mid frequency CMOS temperature compensated crystal oscillator (TCXO). It is ideal for many applications that require stability and accuracy in one compact package. The oscillator utilizes a temperature feedback loop to adjust the oscillation frequency and thus maintain a constant frequency output over temperature. This makes it suitable for a wide range of applications, including precision timebase and phase-locked loop clock synchronization, switching and data conversion clocks, instrumentation, and mixed signal applications.
