摘要:

以Spartan-3E系列FPGA为核心控制模块,结合AD10242模数转换芯片和MXP-123MD-F光收发模块,实现了高速数据采集和光纤传输。其中FPGA用于实现数据控制、双口RAM和8B/10B编解码等功能。该数据采集控制模块具有性能可靠、实时性强、集成度高、扩展灵活等特点,并且通过试验验证了其功能的正确性。

关键词: 数据采集, FPGA, 8B/10B编解码, 光纤传输

Abstract:

This data acquisition control module adopts the FPGA of Spartan-3E serials,AD10242 converter and MXP-123MD-F optical transceiver to realize high-speed data acquisition and optical fiber transmission.In this module,the FPGA acts as the kernel part to achieve functions of data control,dual-part RAM,8B/10B encoding/decoding and so on.This module has the characteristics of stability,good real-time performance,high integration and flexible expansibility.Its function has been validated through test.

Key words: data acquisition;FPGA;8B/10B encoding/decoding;optical fiber transmission
