W5200 no link

Hi,

I’m trying to get W5200 to connect to the internet without results.
SPI works fine. The chip version is ‘3’.
Voltage at any pin is the same like in WIZ820io R1.0.
I have absolutely no link between chip and the pc/router.

I used transformer: tme.eu/pl/Document/3b4751156 … trafot.pdf.

This transformr works fine with WIZ820io R1.0.

Maybe it is problem with hardware?

Hi,
I think your schematic & Hardware may be ok.

Check the switch on/off connected with LINKLED/SPDLED/DUPLED/MODE3.
The switch should be always on.

Thank you.

Thank you for your response.

RA1 and RA2 are resistor arrays. They are always on :slight_smile:
Datasheet resistor arrays:

Best regards.

This may be helpful:

the value from PHY register is 0x07.

Any idea?

You mean 0x07 the value of PSTATUS at 0x0035?
If yes, PHY Link is off.

It maybe your hardware have some problem?

Check the hardware validation again.

Assemble part & value,
Is Reset, Clock siginal worked?
etc…

Thank you.
