TG1612SAN is a high-precision and high stability crystal oscillator launched by EPSON, which offers two versions: TCXO (temperature compensated crystal oscillator) and VC-TCXO (voltage controlled temperature compensated crystal oscillator). It can output frequencies ranging from 13MHz to 52MHz, with standard output frequencies of 16.369MHz and 26MHz. In addition, this crystal oscillator has a fast start function, with a maximum oscillation start time of only 2ms. The packaging size of TG1612SAN is 1.6 × 1.2 × 0.65mm, which is currently the smallest in volume among active crystal oscillators.

Temperature compensated crystal oscillator (TCXO) is widely used in some high-end digital communication product fields, such as GPS global positioning system, smartphones, WiMAX, cellular and wireless communication products, due to its advantages of stable product performance and high accuracy. VC-TCXO products are applied in smartphone crystals, infinite base stations, precision instruments, GPS satellites, automotive applications, and more. EPSON's product TG1612SAN has supply voltages of 1.8V, 2.8V, 3.0V, and 3.3V respectively. Can work reliably in temperature environments ranging from -30 ℃ to+85 ℃ or -40 ℃ to+85 ℃.

Within the normal operating temperature range, the frequency temperature characteristics of its highly stable version can reach ± 0.5 × 10-6, which is suitable for high reliability applications such as GPS; The frequency temperature characteristic of the standard version is ± 2.0 × 10-6, suitable for RF circuits. The frequency aging in its first year does not exceed ± 1.0 × 10-6 when the output frequency is 13MHz~40MHz, and ± 1.5 × 10-6 when the output frequency is 40MHz~52MHz. Its frequency aging rate is low and the output is stable. Attention: In order to maintain stable operation, a bypass capacitor of 0.01~0.1uF should be added near the power input terminal of the crystal (between VCC~GND).
