Jauch Quartz offers a temperature compensated crystal oscillator (TCXO) !!

The JT21G has been developed especially for use in navigation systems (GPS, GNSS etc.).

Particular strengths of the new Jauch-TCXO are:

  • With its enormous frequency stability of ± 0.5 ppm and its low temperature hysteresis of 0.6 ppm, the JT21G meets the high requirements of all common navigation systems.
  • The JT21G can be used in a temperature range from -40°C to +85°C.

  • For battery-powered applications, Jauch additionally offers the JT21GE. This variant  is equipped with an E/D function to disable the TCXO and switch its output to high impedance. Power consumption is thus reduced from 2 mA in normal operation to just 5.5 µA.
