DRM2: the readout board for the ALICE TOF upgrade

For the upgrade of the ALICE TOF electronics, we have designed a new version of the readout board, named DRM2, a card able to read the data coming from the TDC Readout Module boards via VME. A Microsemi Igloo2 FPGA acts as the VME master and interfaces the GBTx link for transmitting data and receiving triggers and a low-jitter clock. Compared to the old board, the DRM2 is able to cope with faster trigger rates and provides a larger data bandwidth towards the DAQ. The results of the measurements on the received clock jitter and data transmission performances in a full crate are given.
