Per HX3 design guide, we learn PCB trace length must under 11" on downstream port.

How about the maximum PCB trace length of upstream port ?

Hi Kyle,

Thanks for posting in the Infineon Developer community!

HX3 SS lines(irrespective of Upstream or Downstream) are characterized for a trace length of up to 11 inches.

Thanks,
Ajeeth

Hi Ajeeth,

How about the maximum PCB trace length of USB2(D+/D-)?

Hi Kyle,

The same trace length is applicable for HS(D+/D-) lines as well for HX3.

Hi Ajeeth,

One more question, what is the maximum HS(D+/D-) trace length of HX3 if we don't consider SS. For example, we connect the one of DS port to connector with HS only signals, without SS signals.

Hi Kyle,

The Trace length for HX3 HS lines should be within 11 inches whether you use SS lines or not.
