Abstract	The GigaBit Transceiver (GBT) architecture and transmission protocol has been proposed for data transmission in the physics experiments of the future upgrade of the LHC accelerator, the SLHC. Due to the high beam luminosity planned for the SLHC, the experiments will require high data rate links and electronic components capable of sustaining high radiation doses. The GBT ASICs address this issue implementing a radiation-hard bi-directional 4.8 Gb/s optical fibre link between the counting room and the experiments. The paper describes in detail the GBT-SERDES architecture and presents an overview of the various components that constitute the GBT chipset.
