Hi
I want to use w5500 chip in my new design
I don’t understand why TD+ of RJ45 connector connected to Pin1(TXN) of W5500 (+ to -)?
TD+ → TDN
TD- → TDP
RX+ → RXN
RX- → RXP
HI.
What you use to RJ-45?
follow this URL → wizwiki.net/wiki/doku.php?id=pro … fschematic
This URL is W5500 Reference circuit
TD+ → TXP
TD- → TXN
RD+ → RXP
RD- → RXN
Thank you
Hi.
your question result is possible.
But, if you create new board see the W5500 Reference circuit.
I think. there is Auto MDI or MDI-X signal to internal of HUB and PC.
This feature is possible for signal matching.
Do you use to WIZ550WEB module?
And what you create to application?
Thank you
Hi
–Do you use to WIZ550WEB module?
Yes, I use it as evaluation board
-And what you create to application?
I build instument with LAN connection
Thank you very mach
But really
Why in Wiz550WEB (+) and(-) exchanged
error?
Thank you
Hi
It is Not error
there is function to AutoMDI/MDI-X in PHY chip.
This function is Possible to TD+,- RD+,- signal matching.
But, you new create product by
TD+ → TXP
TD- → TXN
RD+ → RXP
RD- → RXN
please signal matching.
but W5500’s PHY can not support Auto-MDI/MDIX!!!
Hi.
It is possible to other side to Auto MDI/MDIX. (other side of Ethernet)
