Oscillators: 353TB5A250R

Application Field

The 353TB5A250R is a temperature controlled crystal oscillator (TCXO) that provides superior frequency stability through its internal temperature compensation. It is specifically designed for use with telecom and communication systems, test and measurement systems, metering systems, medical devices, and instrumentation.The 353TB5A250R offers high frequency accuracy of 0.2 ppm, a wide operating temperature range of -40°C to +85°C and a low current consumption of 0.3mA. This makes it ideal for applications that require a reliable, stable output with low consumption and low thermal drift.

Working Principle

The 353TB5A250R is a temperature compensated crystal oscillator (TCXO). It is used to provide a highly-stable frequency output, usually for use in timing, synchronization and control applications.The device utilizes a quartz crystal and a temperature compensating circuit to maintain precise frequency operation over a wide temperature range. The temperature sensitive NPN transistor in the oscillator adjusts its characteristics in response to temperature variations, providing highly-stable frequency operation throughout the entire operating temperature range.The frequency output from the oscillator is proportional to the resonant frequency of the quartz crystal. This frequency is highly-stable over temperature, but still susceptible to frequency changes due to aging and shock. To compensate for these effects, a frequency trimming circuit is used to adjust the frequency and achieve the desired accuracy over time and operating temperature.The 353TB5A250R is also equipped with an integrated voltage controlled oscillator (VCO) for frequency pull range control. The VCO can be controlled via a voltage ramp “up” or “down” for fine adjustments.

Conclusion

The 353TB5A250R temperature compensated crystal oscillator is an ideal solution for applications that require a reliable and stable frequency output with low power consumption and low thermal drift. It offers high accuracy of 0.2 ppm and a wide operating temperature range of -40°C to +85°C, making it a robust and reliable choice for communications, test, instrumentation and medical applications.
