Hello,
I am working with a custom board using W5500 and I noticed some key differences between this schematic versus the evaluation board one - W5500-EVB. I have listed them below:
-
Does leaving the “RSVD” pins (Especially pin 23) NC have an affect on the performance of the chip or anything else? I noticed they are pulled down in the eval board.
-
Pin 37 (nRST) is pulled high in the eval board. I was wondering why it would be pulled high? Our processor controls it and we have pulldown to make sure it is reset on power up
-
RXP and RXN signals have 6.8nF caps each in series with their connector. We don’t have these caps, I am assuming these are for removing the DC aspect of the signals. We are using this connector: 74984104400. Could this be an issue?
-
There is a current limiting resistor (R30 - 10 ohm) on the TXP pin in the evaluation board, we don’t have this. Could this be an issue?
-
Lastly, we are using 0.1uF instead of 22nF for C17 and C26. Could this be an issue
