New ADC FMC board for PROMETEO manufactured in South Africa

An improved version of the ADC FMC trigger board to be used in the PROMETEO test-bench has been in development at Wits University. PROMETEO is the next generation test-bench system that will be used for the full certification of the upgraded front-end electronics of the ATLAS's Tile Calorimeter at CERN.

The board was developed to filter and digitise analog trigger signals coming from the front-end electronics of the TileCal. It makes use of two ADC571 chips to sample 16 differential analog signals at 40 MHz using a 12-bit resolution.  A Xilinx VC707 dev-board with a Virtex-7 FPGA is used for the control and data read-out of the ADC board. The 16 data channels to the FPGA have a combined data rate of 7680 Mbps.

Two fully assembled ADC FMC trigger boards were delivered to Wits yesterday. Oscar Kureba and Matthew Spoor are currently in the process of testing the functionality of the boards. Matthew will be off to CERN next week, where integration of the board with the rest of the PROMETEO components will take place.
