  In synchrotron radiation experiments, some measurements such as nuclear resonant scattering, time-of-flight, and time-resolved measurements necessitate an RF clock and fundamental revolution frequency (zero-address) signals synchronized with a storage ring. Currently, these timing signals are delivered directly over dedicated cables from an accelerator timing station to each experimental station. Considering the upcoming IoT era, it is preferable that these signals can be distributed over a network based on digital technology. Therefore, I am building a proof of concept system (PoCS) that will achieve distributions of the 508.58 MHz clock and the zero-address signals synchronized with the storage ring using RF over White Rabbit*. The PoCS consists of a master node, which receives the RF clock and the zero-address signals from the accelerator, and two slave nodes which generate timing signals near experimental stations. Each node employs a SPEC** board and a new FMC DDS***. The slave node will be able to output the RF clock with the arbitrary division rate and phase after reproducing the 508.58 MHz clock. This paper will describe the achieved functions and performance of the PoCS.
