Hello
https://community.cypress.com/message/35996#35996
Regarding the above community Link, there is a answer below.
>CyU3PUsbSetTxSwing API sets the Tx amplitude used by FX3 on the USB 3.0 interface.
>Please use this API with caution. The device has only been tested to work properly under the default swing setting of 0.9V (swing value set to 90).
>This API is expected to be called before calling the CyU3PConnectState() API to enable USB connections. (swing TX Amplitude swing in 10 mV units. Should be >less than 1.28V)
>
Qestion) Where is this 0.9V measured result? I think it is an IC output pin, but is it correct? Or is it the end of the USB cable (= HOST side)?
Best Regards

Hello,
CyU3PUsbSetTxSwing API sets the Tx amplitude used by FX3 on the USB 3.0 interface. You can set the swing in between 0.9V and 1.28V. This value that is set for the swing can be measured at the SSTX+ and SSTX- pins of the FX3. SSTX+ is the A5 pin and SSTX- is the A6 pin of FX3.
