如何将异步数据读取到FX3

嗨，大家好，
我在FX3设计中有一个关于数据采集的硬件问题。
例如，我有一个ADC，它有两个输出：ADC时钟和与时钟同步的并行数据。由于它是CYSUB3014芯片的一个外部时钟，所以我们说数据速率是100MS/s。我应该如何配置CYUSB芯片来正确读取数据？问这个问题的另一个方法是：如何确保CYUSB（使用GPIF II）的采样时间与外部ADC时钟同步。
如果ADC时钟被固定为104MHz，那么如果我使用分频器产生52MHz时钟作为CYUSB参考时钟，这样，数据采集时间会自动同步到ADC时钟吗？
谢谢您。

  Hi all,
    I have a hardware question about data aquisition in FX3 design.
    For example, I have an ADC which has two output: the ADC clock and parallel data which is synchronized to the clock. Since it is an external clock to CYUSB3014 chip, lets say the data rate is 100MS/s. How should I configure the CYUSB chip to read the data correctly?  The another way to ask this question is: how to make sure the sampling time of the CYUSB (using GPIF II) is synchronized to the external ADC clock.
    If the ADC clock is fixed to be 104MHz, then if I use a divider to generate a 52MHz clock to be the CYUSB reference clock, in this way, will the data acquisition time automatically synchronized to the ADC clock?
    Thank you.
