A multi-purpose 128-channel Time to Digital Converter (TDC) electronics based on the HPTDC [1] with on-board DAQ functionality has been developed, and sucessfully integrated into the data aquisition of the HADES detector (TRBv1, triggered readout board). Currently, a new version has been designed which has a general-purpose connector (for detector-specific operations) and an optical link (2GBit/s), as a replacement of the HADES trigger bus.
In addition, a large FPGA (Xilinx Virtex LX40) and a TigerSharc DSP will add on-board resources for trigger algorithms.
While the main usage of the TRB will be in the context of the RPC-detector upgrade (2600 channels with a needed time resolution of < 100 ps), the TRB will serve in addition as the new general readout board for the replacment of the existing Hades-DAQ.
This poster will give an overview of the status of the TRB-project, and the concept of the new trigger and readout system.
