Part Number: DP83867IS Tool/software: Hi TI Team,
We are using the DP83867ISRGZR in one of our designs, where it is connected to a MAC through an SGMII interface. Unfortunately, we have encountered a link-up issue in a few of our boards (5 out of 15…

Hi Team,
This question about DP83867IS and DP83867IR.
The customer is using it in Three-supply mode(1.1V, 1.8V, 2.5V). They understand that the correct power on sequence should be to ramp…
Hello,
It appears that there are some general board design questions that you are raising. I would like to make aware of a great document for this, SNLA387 , and SNLR048A which can give good rules of thumbs collected over the years.
Placement of SGMII…
Part Number: DP83867IS Hi team,
Could you let me know the minimum T1 requirement of DP83867IS?
In the datasheet, only NOM 200ms is specified.
Best regards,
Kazuki Itoh
Part Number: DP83867IS The Recommended Operating Conditions for VDD1P0 are 0.95 to 1.155V, but is there any problem with supplying 1.1V? We would like to operate at 1.1V to consolidate power supply types.
Part Number: DP83867IS The data sheet states, "When operating in three-supply mode, the 1.8-V VDDA1P8 supply must be stable within 25 ms of the 2.5-V VDDA2P5 supply ramping up. There is no sequencing requirement for other supplies when operating in threesupply…
Hi Hillman
I was referring to pins 1 & 10 of TMUX4212.
TMUX on other side of the transformer is not feasable
TMUX is not pulling MDI lines to certain DC voltage. We are currently only working with offset provided by the DP83867IS and no second ethernet…
Part Number: DP83867IS Other Parts Discussed in Thread: DP83867E Hi
We would like to use the TI part DP83867ISRGZ Ethernet Phy for our new design, which will support both SGMII & RGMII.
Now the design we are focusing is for supporting SGMII.
While referring…
Part Number: DP83867IS Dear Support team,
The DP83867ISRGZ peak voltage signal integrity results are as follows.
Is there a register that can solve this problem?
Thanks.
