TCXO (Temperature Compensation Xtal Oscillator), also known as temperature controlled crystal oscillator, is an active crystal oscillator that achieves high precision and stability through an internal temperature compensation circuit. It is commonly used in scenarios that require high frequency accuracy, such as smartphones, GPS, wireless communication modules, and microcomputer stations (FemtoCell).

TCXO integrates a fixed frequency AT type crystal oscillator internally. Due to the material properties of the crystal, the oscillator has a certain temperature frequency characteristic. At the same time, this characteristic causes the frequency of the crystal oscillator to change with temperature when it is affected by temperature.

TG2520SBN 26MHz is a high stability, low noise, wide power supply voltage (1.7 to 3.63V), 2520 package temperature compensated crystal oscillator, 4-pin surface mount, small-sized crystal oscillator. It can operate stably within a temperature range of -40 to+85 ° C. This model has been discontinued, and it is recommended to use TG2520SMN 26MHz as a substitute material.

Widely used in global positioning systems, radio frequency, wireless communication devices (CDMA, WCDMA, LTE, WiMAX, etc.).

TG2520SMN 26MHz+/-1.5 ppm crystal oscillator is a temperature compensated crystal oscillator with a rated frequency of 26MHz from EPSON/Epson. It is packaged as a 2520 temperature compensated crystal oscillator and has a 4-pin surface mount. It has a small size and high stability. It can operate stably within a temperature range of -40 to+85 ° C, with a power supply voltage of 2.66 to 3.465V.

Due to the advantages of stable product performance and high accuracy, it is widely used in some high-end digital communication product fields, such as GPS global positioning system, smartphones, WiMAX, cellular and wireless communication products.

TG-5006CG-12H 26MHz: 2520 package temperature compensated crystal oscillator, 4-pin patch, with small size and high stability. It is one of the best-selling models in EPSON/Epson temperature compensated crystal oscillator. This crystal oscillator has a power supply voltage (1.7 to 3.465V) and can operate stably within a temperature range of -30 to+85 ° C, with a frequency tolerance of+/-2.0 ppm.

Due to its stable performance and high accuracy, the product is widely used in some high-end digital communication product fields, such as GPS and wireless communication devices (CDMA, WCDMA, LTE, WiMAX, etc.).
