In 2017 a new pixel detector was installed in the CMS detector. This so-called Phase-1pixel detector features four barrel layers in the central region and three disks per end in the forwardregions. The upgraded pixel detector requires an upgraded data acquisition (DAQ) system to accepta new data format and larger event sizes. A new DAQ and control system has been developedbased on a combination of custom and commercial microTCA parts. Custom mezzanine cards onstandard carrier cards provide a front-end driver for readout, and two types of front-end controllerfor configuration and the distribution of clock and trigger signals. Before the installation of thedetector the DAQ system underwent a series of integration tests, including readout of the pilot pixeldetector, which was constructed with prototype Phase-1 electronics and operated in CMS from2015 to 2016, quality assurance of the CMS Phase-1 detector during its assembly, and testing withthe CMS Central DAQ. This paper describes the Phase-1 pixel DAQ and control system, along withthe integration tests and results. A description of the operational experience and performance indata taking is included.
