Abstract:

In the storage ring RF system of Shanghai Synchrotron Radiation Facility, the clock distribution and the local oscillator are two parts of the digital low level radio frequency hardware board. In this paper, we designed and produced the clock distribution and the local oscillator board using the AD9858 and AD9510 chips. The results show that the phase noise of the local oscillator signal is lower than 100dBc/Hz with 50 kHz offset.
