Part Number: DP83867E
Tool/software:
For DP83867, and all RGMII PHYs within our portfolio, all pins marked with TX prefix (TX_D0-3, TX_EN, TX_CLK) are inputs to the PHY when operating in RGMII. The only timing specifications that are required for the…
Part Number: DP83867E Tool/software: We intend to replace now obsolete Marvell 88E1116 Gigabit Ethernet PHY with equivalent part from TI. We have identified part# DP83867E which is not pin to pin compatible with Marvell part and needs a respin of existing…

The following FAQ applies to the DP83869HM and all versions of the DP83867: E/IS/CS/IR/CR
The Analog Supply pins (VDDA2P5 & VDDA1P8) power the MDI portion (connector…
Hi Chiehi,
I am not sure if my understanding is wrong for your measurement. PHY clock (XI pin) should be 25MHz instead of 625MHz.
Regarding to the SGMII measurement, the waveform is not too clean. May I ask where did you probe this measurement? Which…
Part Number: DP83867E Tool/software: I am bit confused about the VDDIO of DP83867E. Section 6.3 Recommended Operating Conditions says three options for VDDIO namely 3.3V option, 2.5V option and 1.8V option. Does it mean one of these options has to be…
Part Number: DP83867E Tool/software: We are using the DP83867E in combination with the Zynq Ultrascale+.
The interface we are using is SGMII, and there are no issues with normal communication.
However, when we apply static electricity, the link is…
Hi Rex,
Thank you for confirming. The problem follows the part. Do you have an FAE you can reach out to report this? I believe we should submit these failed units for Failure Analysis.
