For the Belle II PXD Collaboration.

The data acquisition system for the Belle II DEPFET Pixel Vertex Detector (PXD) is designed to cope with a high input data rate of up to 21.6 GB/s. The main hardware component will be AdvancedTCA-based Compute Nodes (CN) equipped with Xilinx Virtex-5 FX70T FPGAs.

The design for the third Compute Node generation was completed recently. The xTCA-compliant system features a carrier board and 4 AMC daughter boards.

First test results of a prototype board will be presented, including tests of (a) The high-speed optical links used for data input, (b) The two 2 GB DDR2-chips on the board and (c) Output of data via ethernet, using UDP and TCP/IP with both hardware and software protocol stacks.

*This work is supported by BMBF under grant 05H10RG8.
