不同时钟域的问题

嗨，
在阅读了大量文件和无数次尝试之后，我不得不向你寻求指导。
我有一个安装了Spartan XCS1400A FPGA的ZESTET1以太网板。
该板具有1 Gbps以太网接口和TCP-IP卸载引擎。
我的主要目标是将该板与模拟器件AD9229 ADC接口，ADC具有串行LVDS接口，传输速率为480 Mbps。
生成DDR数据时钟和帧时钟用于数据捕获。
ZESTET1板运行频率为125 MHz，但ADC的数据时钟为240 MHz，因此我无法实时获取数据并通过以太网卡流式传输。
我尝试使用FIFO，但我失败了。
Seriosuly我创造了一个巨大的群众。
任何想法和指导都表示赞赏。
谢谢你的时间。

Hi,

After reading lots of documents and countless tries I had to ask for your guidance.

I have a ZESTET1 Ethernet board with Spartan XCS1400A FPGA installed. This board has 1 Gbps ethernet interface and a TCP-IP offload engine. My main goal is to interface this  board with Analog devices AD9229 ADC, ADC has serial LVDS interface and a transfer rate of 480 Mbps. A DDR data clock and frame clock is generated for data capturing. ZESTET1 board runs at 125 MHz, but the data clock of ADC is 240 MHz so I am having trouble acquiring data and streaming it through ethernet card in real time. I tried using FIFO but I failed. Seriosuly I created a big mass.

Any ideas and guidance are appreciated. Thanks for your time.
