Isolated USB programmer for lpGBT (UPL) for the ATLAS-HGTD upgrade

The CERN developed radiation-tolerant data transmission chip lpGBT will be used on the peripheral electronics board (PEB) of High Granularity Timing Detector (HGTD) in ATLAS. In order to configure the lpGBT on the PEB at the debugging stage, we designed a dedicated isolated USB programmer(UPL). Compared with the 2 existing lpGBT configuration toolkits, piGBT and CERN USB-I2C dongle, the programmer has very good cross-platform compatibility, electrical isolation performance and compact dimensions, which make it a better choice for PEB configuration.
