578R100ITT Applications Field and Working Principle

The 578R100ITT oscillator is a family of highly stable temperature compensated quartz crystal oscillators (TCXO) for low power microcontroller (MCU) applications. Dedicated to meeting requirements of demanding automotive, industrial, medical and telecommunications markets, this family of TCXOs features a wide frequency range, low current consumption and extended temperature range.

This oscillator family is capable of providing customers with reliable operation in the most challenging conditions. The 578R100ITT features a temperature range of -40°C to +100°C, making it ideal for applications in a wide range of conditions and climates. In addition, it offers a frequency range of up to 50 MHz and a current consumption as low as 8mA.

The working principle of the 578R100ITT is based on the use of a piezoelectric quartz crystal, which acts as the oscillator’s “personality”. The crystal is housed in a hermetically sealed package that has been designed to minimize waveform distortion resulting from environmental influences. The plate electrodes of the crystal are connected to a capacitor to provide a controlling electrical network. Voltage is applied to the crystal, which produces an oscillation that the controlling electrical network channels and amplifies.

The 578R100ITT’s hybrid circuit is constructed to detect the temperature level and then make the necessary adjustments to keep the TCXO stable and operational. Using oscillator calibration techniques, the oscillator can be accurately set to ensure that it performs correctly and maintains stability even in the most challenging environments. The calibrated circuit ensures that the device’s frequency response is stable over time.

The 578R100ITT is most commonly used in embedded systems, including automotive and mobile applications. The added protection against environmental influences makes it a preferred choice for battery-powered devices, as it ensures that their performance is not impacted by temperature fluctuations. The TCXO also offers improved accuracy when compared to traditional oscillators, making it suitable for applications requiring high precision.

Since the rise of the Internet of Things (IoT), the 578R100ITT oscillator has become increasingly important for ensuring that IoT enabled devices such as connected cars, home appliances, and medical equipment operate accurately and consistently. Due to its long life, ultra-low current consumption, and excellent stability, it is a highly reliable oscillator for embedded systems that demand reliability under harsh environmental conditions.

In conclusion, the 578R100ITT oscillator offers a wide range of features and benefits, making it a preferred choice for embedded systems applications, particularly for use in harsh environments. It offers excellent frequency stability over time, low current consumption, and a wide temperature range. In addition, it is easy to use and calibrate for improved accuracy.
