One important function of many new energy vehicles is navigation. To ensure the high precision and stability of the navigation module, not only does it require a good positioning system, but also a high-performance crystal oscillator. The precision, operating voltage range, operating temperature range, jitter, and packaging parameters of the crystal oscillator should be able to meet the requirements of vehicle specifications very well.

If the navigation accuracy of a car driving on the highway is inaccurate, it is easy to miss some branching intersections, which brings great trouble to travel. An important measure to improve navigation accuracy is to use high-precision crystal oscillators to provide clock signals to the system.

The TG2016SKA launched by EPSON is a temperature compensated crystal oscillator (TCXO) designed specifically for applications such as in car navigation and V2X (TCU, DSRC); The frequency deviation of the temperature compensated crystal oscillator remains within ± 0.5ppm over a wide operating temperature range of -40 ℃ to+105 ℃. Although some crystals on the market are also high-precision, they do not have temperature compensation function and can achieve high accuracy within the normal temperature range. However, the frequency deviation in the entire working temperature range will be large. The low frequency deviation of TG2016SKA in the entire temperature range provides strong guarantee for navigation accuracy.

The current mainstream size of crystal oscillators is 3.2 × 2.5 × 1.2 mm. In some products with very compact PCB areas, it is difficult to place an additional ceramic capacitor. If the size of the crystal oscillator can be further reduced, it can be applied in some portable products. The external dimensions of TG2016SKA temperature compensated crystal oscillator are 2.0 × 1.6 × 0.7 mm, with only 0.4 times the original PCB area occupied and a thickness reduced by 0.5mm.

The TG2016SKA temperature compensated crystal oscillator complies with the AEC-Q100 vehicle specification standard, supporting an output frequency range of 13MHz~55MHz and a working temperature range of -40 ℃~+105 ℃. The typical phase jitter value at 26MHz is 0.13ps. The frequency characteristic parameters of the product are as follows.
