Dose SerDes IO Cells of C6657 have failsafe?

j-breeze

Hi Champs,

According to c6657 data manual [sprs671c] page-123, the IO cells powered by DVDD18 and DVDD15 are not failsafe.

How about SerDes IO cells?
Dose HyperLink / PCIe / SGMII / SRIO / AIF SerDes IO cells powered by VDDR1~6 have failsafe?

I'd like to make sure about that.
Thanks in advance for your cooperation.

Best regards,

j-breeze,

The SERDES IO pins are not failsafe (i.e. not hot-swap tolerant). You will need to put a separate device on these pins if this is a board requirement.
