Hello,
Schematic reviews typically take a 5 working day turnaround. I will look to have feedback by CoB 12/15/21/
Sincerely,
Gerome
Hi Gerome,
Kindly do this schematic review on priority basis, as we are running out of time.
Thanks in advance.
Hello,
The earliest I can pull to give a commit date would be 12/13/21. Would this work with your timeline?
Sincerely,
Gerome
Hello,
I can check if that is possible on my side, but in case, I would expect 12/13/21 latest in case.
Sincerely,
Gerome
Hello,
My feedback:
- Add another 10nF/1uF network on VDD1P0 rail
- Ensure VDD1P8 pins are not shorted together
- Change GND isolation capacitor to 4.7nF and DNP varistor
- Ensure XTAL load caps are appropriate per xtal datasheet
- Does NM mean "Not mounted"? Ensure that MDC is not pulled up.
- No need to double up on center tap decoupling on PHY side. Single 100nF per center tap is sufficient
- Strapping:
+ Address 5
+ Please change RX_CTRL and GPIO_0 Strapping. Currently mode 2. Unknown RX CLK Skew
- 3.5ns TX Clk skew
- SGMII enabled, mirror mode disabled
Sincerely,
Gerome
Hi Gerome,
Pleased find the my inline responses below,
Add another 10nF/1uF network on VDD1P0 rail
Response:--->>> Added
- Ensure VDD1P8 pins are not shorted together
Response:---->>> It is not shorted.
- Change GND isolation capacitor to 4.7nF and DNP varistor
Response:------>>> 4.7nF added and DNP Varistor added
- Ensure XTAL load caps are appropriate per xtal datasheet
Response:----->>> XTAL load cap are provided as per the datasheet recommendations.
- Does NM mean "Not mounted"? Ensure that MDC is not pulled up.
Response:----->>>> Yes, MDC is in DNP
- No need to double up on center tap decoupling on PHY side. Single 100nF per center tap is sufficient
Response:------->>>> Just provided for the safety purposes only, all are in DNP.
- Strapping:
+ Address 5
+ Please change RX_CTRL and GPIO_0 Strapping. Currently mode 2. Unknown RX CLK Skew
Response:- Strapping will be changed during board bring up time.
- 3.5ns TX Clk skew
- SGMII enabled, mirror mode disabled
All your comments are addressed, Thanks for your valuable feedback @Gerome Thanks....
