The readout chain of the DSSC 1M pixel detector currently built at DESY, Hamburg for the European X-Ray Free Electron Laser is described. The system operates in pulsed operation mode comparable to the new ILC. Each 0.1 seconds 800 images of 1M pixels are produced and readout by the DSSC DAQ electronics. The total data production rate of the system is about 134 Gbit/s. In order to deal with the high data rates, latest technology components like the Xilinx Kintex 7 FPGA are used to implement fast DDR3-1600 image buffers, high speed serial FPGA to FPGA communication and 10GB Ethernet links concentrated in one 40 Gbit/s QSFP+ transceiver.

Abstract
The readout chain of the DSSC 1M pixel detector currently built at DESY, Hamburg for the European X-Ray Free Electron Laser is described. The system operates in pulsed operation mode comparable to the new ILC. Each 0.1 seconds 800 images of 1M pixels are produced and readout by the DSSC DAQ electronics. The total data production rate of the system is about 134 Gbit/s. In order to deal with the high data rates, latest technology components like the Xilinx Kintex 7 FPGA are used to implement fast DDR3-1600 image buffers, high speed serial FPGA to FPGA communication and 10GB Ethernet links concentrated in one 40 Gbit/s QSFP+ transceiver.
