TUSB2E22: compensation level

Hi Jaden,

The TUSB2E11 has 3 GPIO pins to select various EQ settings.

The TUSB2E22 has 2 GPIO pins (EQ0/EQ1).  So, the TUSB2E11 has a greater ability to be fine-tuned. 

I will follow to find if the maximum compensation and minimum compensation is the same between the two.

Hi Nicholaus,

Looking forward to your reply.

Hi Nicholaus,

What is the maximum dB that TUSB2E22 back-end compensation can support, and what is the expected wiring length at 480M rate?

Best Regards,

Hi Jaden,

Sorry, I meant to respond yesterday. You can view the dB loss values for various signal conditioning settings in the TUSB2E11 datasheet in the register map, but it doesn't show data for pin-strap mode.  The TUSB2E22 is only pin-strap.  It is taking a while to find this information.

Hi Jaden,

Here are the signal conditioning values for the TUSB2E22.

Hi Jaden,

What customer/project is this for?  It may be helpful to add [Project][Customer] to the E2E issue.

Hi Jaden,

Let me know this information about project/customer when you get a chance.

Are there any other questions about this issue?  

Thanks,

Nicholaus
