Abstract
The central building blocks of the ATLAS Strip Tracker Upgrade are the staves and petals which host up to 14 modules per side. The incoming data is sent to the EoS and multiplexed by the lpGBT chips on 10 Gbit/s links and sent via optical transmitters (VL+) off-detector. The EoS is a critical component for the upgrade, sitting at a single-point-of failure location. Prototype boards have been designed, manufactured and tested using the first available lpGBT and VL+ prototypes from CERN. We present the first test results and give an outlook towards the production of 2000 boards using these chips.
