Jauch发布新TCXO JT21G为导航应用开发

DEVELOPED FOR NAVIGATION APPLICATIONS: JAUCH QUARTZ RELEASE NEW TCXO

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.
The JT21G is available in the frequencies of 26.0 MHz and 38.4 MHz which are typical for navigation systems. A supply voltage in the range from 1.8V to 3.3V is required to operate the TCXO. The new device is housed in an ultra-compact miniature package measuring just 2.0mm x 1.6mm x 0.7mm. The JT21G has a clipped-sine output and is optimized for low power consumption. It is therefore ideally suited for use in small, portable devices.
Additionally, Jauch Quartz also offers a variant of its new TCXO that is particularly suitable for use in battery-powered applications. The JT21GE is equipped with an additional E/D-function that can be used to put the TCXO into a power-saving mode. In this state the output is switched to high impedance, therefore reducing its current consumption from 2 mA in operational mode to 5.5 µA.
The JT21G & JT21GE are both 100 percent lead-free and RoHS and REACH compliant. Both also comply to conflict minerals regulations.

Jauch发布新TCXO JT21G为导航应用开发

Jauch Quartz正在扩大其产品组合:新的JT21G是一种温度补偿晶体振荡器(TCXO ),专门开发用于导航设备。
基于卫星的导航系统(全球定位系统、全球导航卫星系统等)。对振荡器的精度和频率稳定性要求特别高。新的JT21G符合这些高标准，在-40°C至85°C的温度范围内保证0.5ppm的频率稳定性。因此，即使在最苛刻的外部条件下，TCXO晶振也能实现精确定位。
导航应用在日常生活中经常受到温度波动的影响。因此，在研制JT21G时，特别注意了环境温度对TCXO频率稳定性的影响。JT21G每个温度阶跃的最大变化为0.1ppm(最大2°C)，迟滞最大为0.6ppm，满足所有常见导航应用的要求。
贴片晶振JT21G提供26.0MHz和38.4MHz两种频率，这两种频率是导航系统的典型频率。操作TCXO需要1.8V至3.3V范围内的电源电压。这款新器件采用超紧凑微型封装，尺寸仅为2.0毫米x1.6mm毫米x0.7毫米。JT21G石英晶体振荡器具有削波正弦输出，并针对低功耗进行了优化。具有超小型，轻薄型，低抖动，低功耗，低相位噪声，低电压，低损耗，低耗能，低电平等特点。因此，它非常适合用于小型便携式设备。

此外，Jauch Quartz还提供了一种新型TCXO，特别适用于电池供电的应用。JT21GE配备了一个额外的E/D功能，可用于将TCXO置于省电模式。在这种状态下，输出切换到高阻抗，因此其功耗从工作模式下的2 mA降至5.5 A。
JT21G和JT21GE均100%无铅，符合RoHS和REACH标准。两者都符合冲突矿物法规。
