Jauch發(fā)布新TCXO JT21G為導航應用開發(fā)

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發(fā)布新TCXO JT21G為導航應用開發(fā)

Jauch Quartz正在擴大其產(chǎn)品組合:新的JT21G是一種溫度補償晶體振蕩器(TCXO ),專門開發(fā)用于導航設備。
基于衛(wèi)星的導航系統(tǒng)(全球定位系統(tǒng)、全球?qū)Ш叫l(wèi)星系統(tǒng)等)。對振蕩器的精度和頻率穩(wěn)定性要求特別高。新的JT21G符合這些高標準，在-40°C至85°C的溫度范圍內(nèi)保證0.5ppm的頻率穩(wěn)定性。因此，即使在最苛刻的外部條件下，TCXO晶振也能實現(xiàn)精確定位。
導航應用在日常生活中經(jīng)常受到溫度波動的影響。因此，在研制JT21G時，特別注意了環(huán)境溫度對TCXO頻率穩(wěn)定性的影響。JT21G每個溫度階躍的最大變化為0.1ppm(最大2°C)，遲滯最大為0.6ppm，滿足所有常見導航應用的要求。
貼片晶振JT21G提供26.0MHz和38.4MHz兩種頻率，這兩種頻率是導航系統(tǒng)的典型頻率。操作TCXO需要1.8V至3.3V范圍內(nèi)的電源電壓。這款新器件采用超緊湊微型封裝，尺寸僅為2.0毫米x1.6mm毫米x0.7毫米。JT21G石英晶體振蕩器具有削波正弦輸出，并針對低功耗進行了優(yōu)化。具有超小型，輕薄型，低抖動，低功耗，低相位噪聲，低電壓，低損耗，低耗能，低電平等特點。因此，它非常適合用于小型便攜式設備。

此外，Jauch Quartz還提供了一種新型TCXO，特別適用于電池供電的應用。JT21GE配備了一個額外的E/D功能，可用于將TCXO置于省電模式。在這種狀態(tài)下，輸出切換到高阻抗，因此其功耗從工作模式下的2 mA降至5.5 A。
JT21G和JT21GE均100%無鉛，符合RoHS和REACH標準。兩者都符合沖突礦物法規(guī)。
