  The rapid development in the field of digitizers is leading to Analog-to-Digital Converters (ADC) with ever higher sampling rates. Nowadays many high-speed digitizers for RF applications and radio communication are available, which can sample broadband signals, without the need of down converters. These ADCs fit perfectly into beam instrumentation and diagnostic applications, e.g. Bunch Arrival time Monitor (BAM), klystron life-time management or continuous wave synchronization. To cover all these high-frequency diagnostic applications, DESY has developed a direct sampling FMC digitizer board based on a high-speed ADC with an analog input bandwidth of 2.7 GHz. A high-speed data acquisition system capable of acquiring 2 channels at 800 MSP/s will be presented. As first model application of the versatile digitizer board is the coarse bunch arrival time diagnostics in the free electron laser FLASH at DESY.
