The G-03X is a younger sibling of the flagship G-0Rb and is an evolutionary successor to the crystal clock generator model G-0. The G-03X has an OCXO (Oven Controlled Crystal Oscillator) circuit on board. The OCXO is a small thermostatic chamber used to heat the combination oscillator core and control circuits at a fixed, high-thermal level. This provides stability to the crystal clock, being free from unwanted characteristic variations. As a result, the G-03X is exceptionally stable at +/- 0.1 ppm clock stability, even within severe thermal environments ranging from -20C to 70C!

The crystal master clock generator G-03X can be used with a wide range of digital source components with the same established product quality level achieved by the G-O.
