无法将GTX速率设置为高于6.6 Gbps的值

你好
当我将7系列收发器向导用于Kintex-7设备(XC7K70T)时,我无法将GTX速率设置为高于6.6 Gbps的值。
Kintex-7 GTX应该以11.3 Gbps的速度运行,但似乎只适用于XC7K480T设备。
因此,如果您选择XC7K70T作为FPGA,则无法将其GTX用于超过6.6 Gbps的线路速率!
谁能说出问题是什么?
我正在使用在Win-7上运行的ISE14.2。
谢谢

Hi
When I use the 7-series transceivers wizard for a Kintex-7 device (XC7K70T), I cannot set the GTX rate to a value higher than 6.6 Gbps. The Kintex-7 GTX is supposed to work at 11.3 Gbps, but it seems that this is true only for XC7K480T devices. So if you choose XC7K70T as your FPGA you cannot use its GTX for a Line Rate of more than 6.6 Gbps!!!
Could anyone say what the problem is?
I'm using ISE14.2 running on Win-7.

Thanks

Kintex-7部件中GTX的最高速度取决于速度等级和封装类型。
参见表53中的DS182,您将看到在FB封装(无盖倒装芯片)中,所有速度等级的最大速度为6.6Gbps。
FF(高性能倒装芯片)中的器件速度更快,其中性能随速度等级而增加,-3能够达到12.5Gbps。
XCK70T只有两个封装,它们都是FB封装...请参阅Kintex-7产品表,查看可用的器件和封装组合。

以下为原文

The maximum speed of the GTX in the Kintex-7 parts depends on both the speed grade and the package type. Refer to DS182, Table 53, and you will see that in the FB packages (the lidless flip-chip), the maximum speed is 6.6Gbps for all speed grades. The speed is faster for devices in the FF (high performance flip-chip), where the performance increases with speed grade, with the -3 able to go 12.5Gbps.
 
The XCK70T only comes in two packages, and they are both FB packages... Refer to the Kintex-7 Product Table to see the combinations of devices and packages that are available.
