For a proposed upgrade of the Belle II experiment an R&D program has been established to develop a new vertex detector (VTX) made from a single type of depleted active monolithic pixel detector named OBELIX. The chip will provide two low voltage differential signaling (LVDS) data links with a transmission speed of about 339 MHz. To read out the OBELIX data it is foreseen to utilize optical links based on the lpGBT chip and the VTRx+ transceiver module, both developed at CERN. We will present a first concept of the VTX readout system and discuss its technical requirements.

Abstract
For a proposed upgrade of the Belle II experiment an R&D program has been established to develop a new vertex detector (VTX) made from a single type of depleted active monolithic pixel detector named OBELIX. The chip will provide two low voltage differential signaling (LVDS) data links with a transmission speed of about 339 MHz. To read out the OBELIX data it is foreseen to utilize optical links based on the lpGBT chip and the VTRx+ transceiver module, both developed at CERN. We will present a first concept of the VTX readout system and discuss its technical requirements.File in questo prodotto:
