Abstract

The AMC FMC Carrier Kintex (AFCK) board is a prototype of Data Processing Board (DPB) for CBM experiment. AFCK is open hardware and was designed to be a versatile solution, applicable in multiple systems. In CBM experiment AFCK will serve as a data hub and communication interconnection. One of DPB's functions is synchronization of Front End Electronics (FEE). To provide this functionality, it is necessary to receive the reference clock and timing signals from the Timing and Flow Control system. The received clock after the jitter cleaning will be used as a reference clock for GBT-FPGA based 4.8 Gbps links used for communication with front end electronics. This article will briefly describe AFCK board function in CBM experiment. Afterwards it will focus on jitter cleaning technique based on White Rabbit solution that can be used on AFCK board.
