DAMC-X3TIMER: Status Report on the PETRA IV Timing System Development

At DESY, developments towards the fourth-generation synchrotron light source PETRA IV are ongoing in its technical design phase. This machine upgrade foresees a complete renewal of the accelerator and its electronics for controls, including the timing and synchronization system. As a platform choice for the hardware, MicroTCA.4 has been chosen to become the new baseline.This report will briefly summarize the new timing system concept forthe storage ring and its pre-accelerator chain. Furthermore, we will present the current status of the hardware and firmware development of the MicroTCA.4-based AMC, the DAMC-X3TIMER
