To ensure the high stability of the GPS navigation and positioning module PLL reference clock, an external 26MHz high-precision temperature compensated TCXO crystal oscillator design is generally required. The reason for selecting this temperature compensated crystal oscillator is as follows: the rated frequency point is 26MHz, and the accuracy is within+1ppm under high precision at 25 ℃ at room temperature. It is packaged in a small size. In response to the above design requirements, the EPSON Epson crystal oscillator's TG2016SMN series is packaged in 2016, with a frequency of 26MHz, a power supply voltage range of 2.66V~3.465V, an accuracy of+0.5ppm under normal temperature of 25 ° C+2 ℃, and an accuracy of ± 0.5ppm under full temperature of -40 ° C~85 ℃.

EPSON's TG2016SMN temperature compensated TCXO crystal oscillator has a frequency deviation stability of up to 0.5ppm and adopts advanced technology, which is less affected by external factors. The TG2016SMN temperature compensated TCXO crystal oscillator can provide a frequency range of 10MHz~58MHz, suitable for wireless communication modules (Bluetooth, WiMAX, WiFi, W-LAN, IOT modules, RF, drones and other mainstream frequency points, commonly used frequency points include 10MHz, 13MHz, 16.367MHz, 16.369MHz, 16.8MHz. 26MHz and other commonly used frequency points, providing stable reference clocks for these devices and facilitating different design choices for different users.

The TG2016SMN temperature compensated TCXO imported crystal oscillator is a temperature compensated crystal oscillator that can meet the requirements of miniaturization design and has ultra-high performance. Its packaging volume is only 2.0x1.6x0.73mm, and when using the 16.368MHz output frequency point, its corresponding power consumption is only 1.5mA (usually the power consumption of most TCXOs packaged in this package is about 2mA). Finally, the peripheral design of TG2016SMN is relatively simple, and the power circuit only needs to add a simple bypass capacitor to work, but it does not affect the output clock performance parameters, which improves and saves design space. Therefore, TG2016SMN is chosen for the BeiDou/GPS dual-mode navigation receiver module design.
