Please advise me to improve signal integrity of the USB2.0 on C5504.
Are there any register which can adjust USB2.0 launch amplitude in C5504.
The application board (with approximately 4” trace without common mode choke,
no-series resisters or no-ESD protection diodes) failed USB2.0 near end (TP2)
eye mask test.
The PCB exactly followed the design guide, however, the amplitude was as low as
600 mV against solitary bit.
So, the easiest way it increase launch amplitude by 10 %.
