To meet the High-Luminosity LHC demand for enhanced phase stability and replace the outdated RF and timing distribution system (called TTC backbone), an upgrade to a White Rabbit-based system is planned. A compliance test showed a phase variation of less than 30 ps in a proof-of-concept system. In order to assess the quality of the new system in real conditions a test campaign was started in several points of LHC monitoring its phase stability with respect to the RF-master frequency and comparing it to the TTC backbone currently in operation. The test campaign will be described and results presented..
