Stanford CG635 Synthesized Clock Generator
2 GHz low-jitter clock generator (Distributed only in Germany.)
Operation
Choice of Timebases
The standard crystal timebase has a stability of better than 5 ppm. The CG635’s 10 MHz timebase input allows the instrument to be phase-locked to an external 10 MHz reference. The 10 MHz output may be used to lock two CG635s together.
There are two optional timebases. An oven-controlled crystal oscillator (OCXO) provides about 100 times better frequency stability than the standard crystal oscillator. A rubidium frequency source provides about 10,000 times better stability. Either optional timebase will substantially reduce the low-frequency phase noise of the synthesized output.
