    What is the highest clock frequency used in CX3

    hao.meng_1995671

      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.
