Development Of Data Acquisition And PXIe Carrier Card Based On FMC Standard

The system test platform usually takes the board as the unit to realize the different targets and functions. The emergence of the FPGA Mezzanine Card(FMC) standard has decoupled the I/O interfaces from the FPGA, thus realizing the modularization of the board design. This practice successfully divided the board into a processing engine(the carrier card) and an I/O engine(th e FMC module),simplifying the I/O interface module design and meanwhile maximizing the reuse of carrier cards.This paper presents the development of FMC universalcarrier card and mezzanine card, which are applied to the data acquisition system.The PXIe carrier card uses PXI Express as the communication interface, and integrates 1GB memory by eight DDR2 SDRAM chips. Also, the carrier card provides high-speed and reconfigurable digital I/O interface through the FMC connector. The carrier card can realize the control of different mezzanine card by designing standardized FMC interface module. The FMC high-speed ADC(I/O) mezzanines module realizes the function of high-speed data acquisition, which can supplies 3GSa/s sampling rate by chip ADC08D1520. The peripheral circuit includes analog front input circuit, high speed differential clock circuit and the card information storage circuit. The overall structure of mezzanine card is designed strictly according to the FMC standard, which can be applied to carrier card with FMC connect for the data acquisition function expansion.To test the performance of the PXIe carrier card on data acquisition applications.We connect universal carrier cards with FMC high-speed ADC(I/O) mezzanines module.Through the test of ADC mezzanine card, the bandwidth of data acquisition is above 600 MHz and in the bandwidth range the ENOB is about 6.5bits.
