Part Number: TIDA-00465 Hello Team,
Am i correct, that the H6096NL transoformer will be in series with the magnetics that I have directly after my ethernet phy?
If yes, do you have any idea on the transmission loss it will add, eg. how much less cabling…
A couple comments regarding the schematics:
Sense resistors look under rated in power. Please use at least 1/4W 0805 sense resistors.
I don't see where PSE_N1 goes, is there another port in the system?
I don't see a series cap on the other…
Thank you for the wait. These are all the TIDA designs that the team could pull in regards to PoE.
For PSE, we recommend our single port reference design: www.ti.com/.../TIDA-00465
Do you have additional design requirements for your PD? (type, output power, topology, efficiency, etc) I can recommend designs.
These PoE pass-through designs are becoming common in PoE PD applications. Unfortunately, we do not have a dedicated TI design. However, the solution can be quite simple.
I recommend taking the TPS23754EVM-383 (12V type 2 PD), and adding a…
In short, in order to make the TPS23861 switch between AF and AT, you need a microcontroller to let the TPS23861 output AF, AT power at the PSE output.
However, if you know that the third block will always be AF then this might not be necessary…
Are you looking to be IEEE802.3 compliant on both the input and output? If so, then yes you will need to do as you suggested a PD at the input and PSE like the TPS23861 in TIDA-00465 (or injector) at the output to connect to the other compliant…
