38.4MHz temperature compensated crystal oscillator focuses on navigation system

With the increasing application of navigation, the environment faced by navigators is also diverse. It is often used in harsh and harsh environments, such as tropical high-temperature environments, or high-latitude low-temperature environments. Car navigation used in automobiles will also face In severely turbulent environments, if the crystal oscillator cannot handle these environments, it will cause the RF module and the main chip to fail to work, and the positioning function will fail. Satellite navigation has been widely used in transportation, communications, electricity, finance, meteorology, marine, and hydrological monitoring. big difference working environment, in order to ensure navigation can work in a variety of environments, a high-stability clock source is essential, this article will introduce the high stability of the temperature compensation crystal oscillator model TG-5006CJ-20H ( X1G004131001100) in Beidou navigation.

Love Cape Health crystal introduced in the TG-5006CJ-20H (X1G004131001100) warming TCXO crystal oscillator frequency is 38.4MHz, the working temperature range of -30 _{to work in a variety of harsh environments + 85 ° C, is very suitable for application of the navigation device , TG-5006CJ-20 with temperature compensation can maintain a high accuracy of ±0.5×10-6 at a temperature of -30°C+85°C. The frequency range of TG-5006CJ-20H is 13} 52MHz. Through pin 1, two functions of voltage-controlled temperature compensation (VC-TCXO) and temperature compensation (TCXO) can be switched, which provides flexibility for user design. The frequency of the crystal oscillator is stable. The performance is very good, the frequency and load, and the voltage relationship coefficient are both ±0.2ppm, the frequency aging in the first year does not exceed ±1ppm, and the frequency tolerance is as low as ±2ppm (after reflow), which can meet some requirements for higher stability Core network equipment application.

TG-5006CJ-20H also has good temperature characteristics. It reduces the influence of temperature changes on the output frequency through temperature compensation. The frequency stability with temperature changes is ±2ppm. In addition, TG-5006CJ-20H also has the characteristics of low power consumption. The working voltage is 1.7V-3.465V, and the current consumption is only 2.0mA. The package size of this temperature compensated crystal oscillator TG-5006CJ-20H from EPSON Epson Crystal Oscillator is 2.0x1.6x0.73mm. The ultra-small package can save design space. Coupled with the advantages of high stability and high precision, TG-5006CJ-20H temperature compensated crystal oscillator can be widely used in radio frequency and wireless communication equipment.
