Oscillators are vital for many electronic device and system designs, providing them with the measure of regularity, frequency, phase and timing accuracy required to operate. The 511EBA125M000BAGR is an example of an application specific oscillator, and this article provides a close look at what it is and how it works.

The 511EBA125M000BAGR is a quartz-based temperature compensated quartz crystal oscillator (TCXO). TCXOs are used in applications where stable frequency performance is required in the presence of wide temperature variations. Within automotive, industrial and communication systems, an acceptable frequency variation is required over a wide range of temperatures. The 511EBA125M000BAGR is designed to provide frequency stability over temperatures from -40°C to 125°C.

As such, applications for the 511EBA125M000BAGR are predominately found within automotive and industrial markets. This includes in-vehicle infotainment, instrumentation, GPS tracking systems, industrial manufacturing process controllers, and also various communication systems.

The 511EBA125M000BAGR has a variety of features that improve its ability to deliver stable, accurate frequencies. Firstly, it has an internal ceramic resonator that is temperature compensated over the full temperature range. This ensures that the frequency will remain as accurate as possible over a wide temperature range. Also, the 511EBA125M000BAGR has a very low stanndby current of 0.05 μA, aiding power efficiency in devices where the oscillator is running but not actively transmitting. The rated frequency of the 511EBA125M000BAGR is 10 MHz with a very tight frequency tolerance of +/-10 PPM. Stated in another way, this is equivalent to a frequency variation of just 1 Hz over the entire temperature range. Low noise is also a feature of the 511EBA125M000BAGR, with a phase noise of -142.5 dBc/ Hz at 10 KHz.

The 511EBA125M000BAGR is an excellent example of a quartz based oscillator that provides reliable frequency stability and phase noise over a wide temperature range. Its low power, tight tolerance, and low noise make it ideal for temperature sensitive automotive and industrial applications. With the ability to reach temperatures of 125°C, the 511EBA125M000BAGR can also be used in demanding environments where reliability and accuracy is required, such as in-vehicle infotainment and communication systems.
