Part Number: TIDA-010046 Hey,
on Page 23 of the design guide TIDA-010046 3V3 is at midpoint of the transformer and between 50 ohm resistors (first schematic for "non-PoE") and the ESD312DBVR is connected to datalines. Does it work correctly and are…
Part Number: TIDA-010046 Other Parts Discussed in Thread: TPS23730 , TPS2372 , TPS2373 Hi Team,
My customer is interested in this reference design, however, they would like to implement >25W PD, do we have recommended alternative part for PD controller…
Part Number: TIDA-010046 Other Parts Discussed in Thread: TPS23754 , Hi,
I am in the proces of designing a PoE+ PD device using a DP83848 and a TPS23754. I have the develoments boards for both these ICs.
I don't want to use a more expensive 4-pair…
Part Number: TIDA-010046 Hi, in this reference design GND and EARTH is coupled with a 1M and a 4700 pF capacitor near the magnetic. Could you please explain the reason why? The documentation says: 'Additional capacitors are required to interconnect chassis…
Part Number: TPS23755 Other Parts Discussed in Thread: TIDA-010046 Tool/software: Hello,
In the reference design TIDA-010046 for TPS23755 the transformer LDT0950-50 is specified. Do you have an alternative for this one?
Best Regards,
Einar
Part Number: TPS23861 Other Parts Discussed in Thread: TIDA-010046 Hi team,
Could you please answer below questions?
1. Is it ok to change SEN1 resistor 22.1 ohm to 22ohm?
2. Is it ok to connect RJ45 and Xfmr as below?
3. Basically, PD device…
Hi Ben,
It is unexpected that DP83825 will have headaches regarding emissions testing. You may consult TIDA-010046 where the board is below Class B and mimic appropriate board design practices as the authors of the app note.
We also have an appnote…
Hi Miguel,
I would recommend the https://www.ti.com/product/DP83822I . We also have this reference design, where the DP83825 is used in RMII repeater with the DP83822: https://www.ti.com/tool/TIDA-010046
In this design the DP8383825 is in RMII Master…
Part Number: DP83825I Other Parts Discussed in Thread: TIDA-010046 In our PD PoE design we are using the DP83825I as PHY. After extensive tests we have found that the link is more reliable leaving the PHY facing tap center of the transformers unconnected…
Part Number: TPS23861 Other Parts Discussed in Thread: TIDA-010046 Hello.
I designed a PSE circuit using TPS23861 and KSZ8041 Even if you connect to a hub (that is not PD), it will not link up. For the connection between the transformer and the connector…
