We are making an updated design of our USB hub solution were we are considering HX3. One customer requirements is that it should support USB Asynchronous audio streaming for their high-end audio solutions. However, we are unsure if that has any dependency on the hub-part of the solution or if it is only a matter for the host and USB-device side? Anything to consider regarding the clock (or similar) for the HX3 and hub?
HX3 is a standard USB hub that meet the USB-IF specification. The only thing you need to consider is that whether the bandwith of the upstream port(USB 3.0 5Gbps) can meet your requirement.
