The ESRF timing system, dating from the early 90's and still in operation, is built around a centralized RF driven sequencer distributing synchronization signals along copper cables. The RF clock is broadcasted over a separate copper network. White Rabbit, offers many attractive features for the refurbishment of a synchrotron timing system, the key one being the possibility to carry RF over the White Rabbit optical fiber network. CERN having improved the feature to provide network-wide phase together with frequency control over the distributed RF, the whole technology is now mature enough to propose a White Rabbit based solution for the replacement of the ESRF system, providing flexibility and accurate time stamping of events. We describe here the main features and first performance results of the WHIST module, an ESRF development based on the White Rabbit standalone SPEC board embedding the White Rabbit protocol and a custom mezzanine (DDSIO) extending the FMC-DDS hardware to provide up to 12 programmable output signals. All WHIST modules in the network run in phase duplicates of a common RF driven sequencer. A master module broadcasts the RF and the injection trigger.
