Epson's TCXO technology occupies an important position in a wide range of application fields such as GPS, wireless communication, automotive, and medical equipment due to its miniaturization, low power consumption, high stability, and high precision. Its TCXO product can maintain excellent frequency stability even in extreme temperature ranges. Epson's TCXO products are widely recognized in the market for their reliability and high performance, and it is expected that their market demand will continue to grow with the development of 5G and IoT technologies.

Epson produces the TG-5006CG high-performance temperature compensated crystal oscillator (TCXO), which plays a crucial role in GPS positioning systems. This TCXO can provide excellent frequency stability of ± 0.5 × 10 ^ -6 within a wide temperature range of -30 ° C to+85 ° C, ensuring that GPS devices can maintain accurate clock signals under different climatic conditions, thereby guaranteeing positioning accuracy. Its compact packaging (2.5 × 2.0 × 0.8 mm) is highly suitable for integration into GPS devices with limited space, such as portable navigators and smartphones. In addition, the low-power characteristics of TG-5006CG (up to 1.5 mA) help extend the battery life of the device, while the fast start-up time (up to 2.0 ms) ensures that the device can quickly acquire satellite signals and accelerate positioning speed.


The TG-5006CG provides a wide voltage operating range (1.7V to 3.465V), enabling it to adapt to different power environments. The built-in temperature compensation circuit can automatically adjust the output frequency to offset the impact of environmental temperature changes on frequency stability, which is crucial for maintaining GPS positioning accuracy in changing environments. This TCXO is designed specifically for GPS and other wireless communication devices such as CDMA, WCDMA, LTE, WiMAX, ensuring high performance and reliability in these applications. Therefore, TG-5006CG has become an ideal clock source choice for GPS devices, providing stable and accurate clock signals, ensuring the high accuracy and efficiency of positioning systems.
