CX3中使用的最高时钟频率是多少

我有一个外围设备，使用CyPress CX3作为桥集成电路，我们正在进行EMC测试提交。我们需要知道在CX3中使用的最高时钟频率，因为它支持在5Gbps的UB3.1 GEN1，我假设它有一个时钟运行在2.5GHz或5GHz内的USP3 PHY。它在2.5GHz和5GHz之间产生了很大的差异，因为FCC标准要求使用5倍的最高频率，并且没有多少个腔室能够达到25GHz。
请让我知道CX3内使用的最高时钟，这样我可以正确地计划我的测试室和测试极限。
谢谢您。

  I have a peripheral device that uses Cypress CX3 as bridge IC, and we are performing EMC tests for submittal.  We need to know the highest clock frequency used in CX3, since it supports USB3.1 Gen1 at 5Gbps, I assume it has a clock running at 2.5GHz or 5GHz inside the USB3 PHY.  It makes a big difference between 2.5GHz and 5GHz, because FCC standards calls for 5 times the highest frequency used, and not many chambers are capable of 25GHz.

Please let me know the highest clock used inside CX3, so I can plan my test chamber and test limit correctly.

Thank you.
