Hi,

There is an issue with the DP83865 with a customer using in conjunction with a switch.

Two particular models of switches yields corrupted data link.

The block diagram is simple.

Xilinx FPGA <-> DP83865 <-> Switch

The gig switch includes the following: dlink dgs 3200-10  and cisco catalyst 3560g-24ts-s.

If the customer inserts a "working" switch between the "failing" switch, the system links correctly and data is transferred without corruption.

Please provide some suggestions. Customer has reviewed the  documented located at   http://www.ti.com/litv/pdf/snla065

The customer has followed the suggestion with no resolutions. Please advise.
