Dears,
We have such a demand for a case, please help to review to see what the solution is: a USB3.0 transmission device, the rate is 5Gbps, the customer requires to be able to monitor the data transmission on the USB path in real time, and realize the flashing signal when the data is transmitted.
Our difficulty is how to detect data transmission on the USB3 path, ADC sampling or there is a transmission channel chip can monitor.
When connecting the monitoring device on the USB path, it is necessary to pay attention to not affecting the USB signal impedance
If ADC sampling, is it necessary to use high-speed ADC, bandwidth of more than 5GHz, the domestic can get this kind of device?The other cost is not super high
The product is a USB dock
The chip inside is only responsible for data transfer, not the terminal, and the hub chip itself does not have the ability to identify data transmission
