Introduction of TC-25.000MCE-T Oscillators

TC-25.000MCE-T is a highly integrated temperature compensated MEMS oscillator (TCXO) developed by HTC Corporation for consumer electronics applications. The TC-25.000MCE-T achieves outstanding frequency stability in temperature applications down to -55°C and offers exceptional system-level frequency accuracy with easily programmable frequency spreads from ±0.5ppm to ±20ppm. The TC-25.000MCE-T is available in 5-pin ceramic package and operates from a 1.8 V to 3.3 V supply voltage.

Application Field and Working Principle of TC-25.000MCE-T Oscillators

The TC-25.000MCE-T is well suited for various consumer applications including navigation, industrial, IoT, wireless, satellite radio, 5G, LTE, and automotive audio. With its designed-in frequency stability over temperature, the TC-25.000MCE-T can improve the performance of consumer electronics products when compared to similar products without temperature compensation.The TC-25.000MCE-T design concept combines MEMS-based resonators, digital temperature compensation and programmable frequency spread, making it one of the most accurate and stable TCXOs on the market. It is a hybrid design that combines the best of MEMS resonator technology and conventional quartz crystal oscillators. By employing MEMS-based technology, the TC-25.000MCE-T is able to maintain stability over temperature and exhibit faster warm-up time when operated in low temperature applications.Due to its small form factor and low power consumption, the TC-25.000MCE-T is ideal for low-power applications. The TC-25.000MCE-T operates at frequencies from 1MHz to 54MHz, making it suitable for a wide range of consumer products. The TC-25.000MCE-T also has an integrated crystal-oscillation IC, allowing for easy integration into consumer products.The TC-25.000MCE-T uses a dedicated digital temperature-compensation circuit to quickly correct the output frequency based on the temperature of the device. This feature allows the oscillator to maintain high frequency accuracy over a wide range of temperatures (-55°C to +125°C) compared to quartz crystal oscillators without temperature compensation. The temperature compensation circuit also reduces the effect of aging of the oscillator over time, resulting in improved system performance.The TC-25.000MCE-T also employs a frequency-spread circuit that allows the user to easily adjust the frequency accuracy of the oscillator +/- 0.5ppm to +/- 20ppm to reduce system jitter and improve system performance. The adjustable frequency spread circuit provides an easy-to-program just-in-time production solution enabling efficient management of manufacturing costs.Finally, the TC-25.000MCE-T has a low-power consumption of 200uW and a fast wake-up time of 60µs, making it ideal for battery and energy storage applications. Additionally, the TC-25.000MCE-T is highly resistant to vibration and shock, making it suitable for automotive, industrial, and consumer applications.

Conclusion

The TC-25.000MCE-T oscillator offers excellent frequency stability over temperature, high accuracy, low power consumption and a very compact form factor. It is an excellent choice for consumer electronics, navigation, industrial, 5G, IoT and automotive applications.
