Description
Summary
The silicon pixel detector of the CMS experiment at CERN will be replaced with an upgraded version in the beginning of 2017 with the new detector featuring an additional barrel- and end-cap layer resulting in an increased number of fully digital read-out links running at 400Mb/s. New versions of the PSI46 read-out chip and Token Bit Manager have been developed to operate at higher rates and reduce data loss. Front-End Controller- and Front-End Driver boards, based on the uTCA compatible CTA AMC which is a variant of the FC7 card, are being developed using different mezzanines to host the high-speed optical links for the digital read-out and control system.
This contribution will give an overview of the system architecture and first experience and results obtained with test systems and a pilot system installed in CMS. Furthermore the validation and deployment of the uTCA backend electronics will be highlighted.
