Special TCXO for navigation systems (GPS, GNSS etc) in miniature SMD package
JT21G is a temperature compensated high stability oscillator with a frequency stability as tight as ± 0.5 ppm.
The standard frequency of this TCXO is 26.0MHz, and it is available in two temperature ranges -30°C ~ +85°C and
-40°C ~+85°C. The available supply voltages are ranging from 1.8V to 3.3V.
Due to the high frequency stability of ± 0.5 ppm the JT21G TCXO meets the special requirements that apply to navigation systems like GPS or GNSS, such as a low temperature hysteresis and a strictly limited temperature slope.
Due to its clipped sine output and its low power design, this TCXO offers a very low power consumption and is particularly suitable for compact handheld and mobile applications.
In addition, JT21GE offers an E/D function to disable the TCXO and switch the output to high impedance.
