Part Number:DP83822I
Hi
I got help before concerning this issue:
DP83822I: Differences between DP83822 and TLK105?.
Geet Modi helped me then.
The reason why we want to leave TLK105 is the CrossTalk when its off. We have buildings there the hole Ethernet Communication goes down when the heatpumps is turned off.
TLK105 has except this issue been very stable and good over the five years until this was discovered.
This is the reason for the change to DP83822.
I attached the schematics before and after the Rollover.
Through software we see now that the bootstrap works and we enter the right mode RMII 50MHz.
But after while we see that the Ethernet Connection goes down and these two registers reach its roof:
Rx CRC Errors: 0
Rx Align/Code Errors: 0
Can you find something in this attached schematic that we need to change or do in the software?
I see in the Rollover that the 50MHz shall go through DP83822 and out on RXD_3 is that important?
I have also read:
TLK110: Link pulse was returned under power off state
