本文描述了一个用于8通道压频转换（VFC）数据采集系统的全数字接口模块，该采集系统具有高信噪比和低的接口定时约束，接口模块用一片现场可编程门阵列（FPGA）芯片实现．除了结构紧凑、工作可靠以外，使用FPGA实现的该接口模块可以多次重新构造，以便适应系统结构或功能上的变化需求．
This article describes an all-digital interface module for an 8-channel VFC data acquisition system with high signal-to-noise ratio and low interface timing constraints. The interface module uses a field-programmable gate array (FPGA) Chip implementation. In addition to being compact and reliable in operation, the interface module implemented using FPGAs can be reconfigured multiple times to accommodate the changing needs of the system architecture or functionality.
