Hi,

I want to evaluate the eye mask of the interface of CYUSB3304 with processor in read and write modes. I have found the IBIS model of this USB hub and now I want to validate that eye mask opening values to check whether the SI is pass or fail.

Please share any reference for the eye mask values for this interface.

Thanks.

Hi,

Thanks for sharing the eye mask details for USB high speed trace SI validation.

I am referring the Silicon version Rev *S for CYUSB3304 HX3 specifications.

Also, I am implementing the CYUSB306X IC and need to validate the CSI 2 lane interface. Can you please share any references for CSI-2 lane eye masks for clock speed in range of 250MHz to 950MHz.

Let me know if I need to start another thread for the CSI-2 Lane query.

Thanks,

Dhara

Hi Dhara,

Yes, please create a separate thread for your query on CYUSB306X for easier tracking.
