| Abstract | The ATLAS experiment requires a high-precision bunch clock distribution for the High-Luminosity upgrade of the Large Hadron Collider. A new trigger and timing distribution system based on FPGA transceivers and high-speed serial links will replace the existing one. In preparation for this upgrade, we characterized the clock phase uncertainty of AMD UltraScale+ transceivers after reset. We found the performance of the GTH type to be adequate, and we implemented a workaround to correct the behavior of the GTY type receiver. In addition, we extensively studied the effect of silicon temperature variations on the phase and implemented a compensation algorithm. |
