LVDS transmission is promoted for the output of TOF Trigger System at BESIII, which can provide enough driving capacity and noise immunity. Considering that there are a large amount of signals, parallel-to-serial/serial-to-parallel scheme is introduced so as to save space and get higher efficiency. A receiving board has been established for test and verification. Combined with FIFOs which are designed for synchronous purpose in FPGA, we successfully get the synchronous receiving of recovered data of multi-channel serial transmission. Thus we have accomplished the aim of fulfilling the fan-out of all the TOF trigger signals on a 9U VME rear transition module. It presents a very good reference solution to transfer mass signals synchronously with high speed in complex instrument systems actually.

Large-capacity data Simulation system is one hand generally used for extreme testing to expose problems in the system being tested, making the system more perfect; the other hand, for leading-edge test and preparation for system being tested to be used under more stringent conditions. The paper, based on the practical application of a cable simulation system for offshore oil exploration, describes in detail the data simulation system's design concepts and the basic implementation, which can be used as a model for such applications, based on FPGA. The proposed framework can also be applied as a design reference model for data acquisition applications.
