单个外部振荡器到多个GTP

大家好，
我有一台带有PCIe功能的Spartan-6 150T设备，我想将单通道Aurora添加到其他未使用的GTP中。
我有两个独立的100MHz低抖动时钟，其中一个用于PCIe GTP，另一个用于Aurora ......
我的问题是：我可以将PCIe时钟用于PCIe，并将其他时钟用于所有7种Aurora实现吗？
是否有其他方案，如将PCIe时钟分配给4个GTP，另一个时钟分配给其他4个GTP？
甚至可以使用另一个GTP时钟的GTP吗？
我不认为分离跟踪并将时钟外部路由到每个GTP时钟输入是有效的。
S-6设备上的全局时钟资源可以在内部将时钟分配给其他GTP吗？
谢谢！

Hi all,

I have a Spartan-6 150T device with PCIe working, and I want to add single-lane Aurora to the other unused GTPs. I've got two separate 100MHz low-jitter clocks, of which one is going to the PCIe GTP, and the other is available for Aurora...

My question is this: can I use the PCIe clock for PCIe, and use the other clock for all 7 Aurora implementations? Is there some other scheme, like distributing the PCIe clock to 4 GTPs, and the other clock to the other 4 GTPs?

Is it even possible to use a GTP from another GTP's clock? I wouldn't think that branching off traces and routing the clock externally to every GTP clock input is valid. Can global clocking resources on the S-6 device distribute the clock to other GTPs internally?

Thanks!
