Jauch - Developed for Navigation Applications Quartz Release NEW TCXO

06 - 07 - 2020

Jauch Quartz is expanding its product portfolio: The new JT21G is a temperature-compensated crystal oscillator (TCXO) that has been specially developed for use in navigation devices.

Satellite-based navigation systems (GPS, GNSS, etc.) are especially demanding regarding precision and frequency stability of an oscillator. These high standards are met by the new JT21G that guarantees a frequency stability of ± 0.5 ppm in a temperature range from -40°C to 85°C. The TCXO therefore enables a precise positioning even under the most demanding external conditions.  

Navigation applications are frequently exposed to temperature fluctuations in everyday life. When developing the JT21G, special attention was therefore paid to the influence of ambient temperature on the frequency stability of the TCXO. With a maximum change of 0.1 ppm per temperature step (maximum 2°C) and a hysteresis of maximum 0.6 ppm, the JT21G meets the requirements of all common navigation applications.
