Here we describe our various AddOn Cards for the TRBv2

HUB-AddOn

The TRB-HUB servers as the trigger fanout-module.
It has 16 times a 2-GBit/s SFP. The SERDESes are in the LatticeSCM40 FPGA.
Fully impedance matched 12-layer PCB.

The General Purpose Add on: Short Description

The General Purpose Add on (GP-AddOn) board povides the interface between the TRBv2 (main readout board) and many different signals. For example it can used as interface to the old HADES trigger bus. The GP-AddOn can be easily connected to the TRBv2 board through 2 connectors (QSE-040-01) placed on the back side of the board. The power supply is given to the GP-Addon through the connector's pins. A programmable logic CPLD ( XCR3128XL7VQ100C) is placed on the right hand side and is supported by Xilinx Web-PACK™ and industry standard CAE tools (Cadence/OrCAD, Exemplar Logic, Mentor, Synopsys, Viewlogic, and Synplicity), using HDL editors with ABEL, VHDL, and Verilog. Design verification uses industry standard simulators for functional and timing simulation. Here we attach the data sheets for further details of the board's component:
