Stanford CG635 Synthesized Clock Generator
2 GHz low-jitter clock generator (Distributed only in Germany.)
Operation
Phase and Time Modulation
The clock phase can be adjusted with high precision. The phase resolution is one degree for frequencies above 200 MHz, and increases by a factor of ten for each decade below 200 MHz, with a maximum resolution of one nano-degree. This allows clock edges to be positioned with a resolution of better than 14 ps at any frequency between 0.2 Hz and 2.05 GHz.
The timing of clock edges can be modulated over ±5 ns via a rear-panel time-modulation input. The input has a sensitivity of 1 ns/V and a bandwidth from DC to over 10 kHz, allowing an analog signal to control the phase of the clock output. This feature is very useful for characterizing a system's susceptibility to clock modulation and jitter.
