VCCT_GXB & VCCR_GXB Ripple Measurements

Hi,

As I understand it, you have some inquiries on the oscilloscope bandwidth to use for XCVR power supplies measurement. For your information, as I search into documentation, there seems to be no specific information on this. Sorry for the inconvenience.

Just to for sharing purpose only, based on my own experience, I have used scope with 500MHz bandwidth.

It is recommended for you to further consult your test or measurement equipment vendor on the right equipment to use for your measurement. I believe they should be the right person to advise you on this.

Please let me know if there is any concern. Thank you.

Hi,

Thanks for your clarification. I understand that your specific inquiry is as following:

"I'm asking what is the maximum frequency of the voltage AC component (voltage regulator ripple, noise, dynamic response etc) that will reduce the FPGA performance?"

As I search into the datasheet, I could not find any specific information on this. We would need to further engage our power expert to see if they have any inside into this.

Would you mind to help me open a new Forum case on this specific inquiry and let me know the case number so that I can help to expedite the routing to power team? Sorry as I am not able to duplicate or open new case from my side and would need your help on this.

Please let me know if there is any concern. Thank you.

Best regards,

Chee Pin

Hi,

Just to follow up if you have managed to open a new case in the Forum. If yes, mind share with me the case number so that I could help to expedite the routing (in case it is still not attended to). Thank you,.

hi,

I've re opened the below case:

please help to promote.

Hi,

Thanks for your update. I have notified the power team to expedite the routing. Sorry for keeping you waiting.

thanks!
