Overall Description of UT Electronic Components

The Upstream Tracker (UT) is a large-area silicon-strip detector being constructed for the LHCb Upgrade. It plays a key role in that it enables a rapid momentum measurement to be performed, and usage of that information increases the speed at which the software trigger operates by about factor of three. The readout system of the UT -- and all other LHCb detectors -- runs at the full LHC beam-beam crossing rate of 40 MHz, allowing every event to be fully analyzed in the software trigger. This talk will present the components of the UT readout electronics, which includes a custom ASIC, Kapton hybrids, flex cables that transport signals to the periphery, and peripheral electronics that process and package the signals for the data acquisition system and experimental trigger. And the data flow within those components will also be briefly discussed.
