Is there a way to disable USB3 Tx SSC on the HX3 USB 3.0 HUB Controller ?

Is there a way to disable USB3 Tx spread-spectrum (SSC) on the HX3 USB 3.0 HUB Controller ? Can SSC enable/disable be done per port or upstream vs downstream ports ?

Hello,

The SSC control settings is set in the firmware and not through configuration by Blaster Plus. Since it is a fixed firmware part, any custom changes cant be made. Please let us know if you have any particular requirement?

Hello Sananya,

Thank you for info. Our purpose is to use HX3 hub with FPGA with direct serial I/O interface (not PIPE), Can you please send custom firmware configuration that does the following so we can test in lab ?

a. US SSC disabled, DS SSC disabled, Hub REFCLK external from clock generator IC.
