The pixel-strip modules for the CMS Tracker Phase-2 Upgrade for the HL-LHC integrate a readout hybrid (PS-ROH) for the control and data acquisition link. This hybrid is based on the new, low power and compact gigabit transceiver (LpGBT) and the versatile transceiver VTRx+ specifically designed for the upgrade. A characterization board was first designed to qualify the design rules and the achievable timing performance of the gigabit block. This design enabled the development of the PS-ROH for the CMS Tracker PS modules. A testing setup was also developed to verify the PS-ROH performance before its integration into the PS modules.
