The DAQ and Timing Hub is an ATCA hub board designed for the Phase-2 upgrade of the CMS experiment. In addition to providing high-speed Ethernet connectivity to all back-end boards, it forms the bridge between the sub-detector electronics and the central DAQ, timing, and trigger control systems. One important requirement is the distribution of several high-precision, phasestable, and LHC-synchronous clock signals for use by the timing detectors. The current paper presents first measurements performed on the initial prototype, with a focus on clock quality. It is demonstrated that the current design provides adequate clock quality to satisfy the requirements of the Phase-2 CMS timing detectors.
