Driving DVI-D with Spartan6 LX45 Fpga
Added by Naveen K.S about 11 years ago
From the following discussion, it is said that Spartan6 LX45 FPGA based MityDSP-L138F SOM cannot drive DVI-D on Industrial IO boards. Is this case true now also or this issue resolved??
Kindly reply as soon as possible.
Thanks in Advance

""DVI Output with MityDSP-L138F w/6SLX45 FPGAs
Added by Wade Calcutt about 1 year ago
Based on the datasheet, models of the MityDSP-L138F SOM that have the 6SLX45 FPGA installed (L138-FI-225-RC, L138-DI-225-RI, and L138-FI-236-RL) have no connects on pins 154, 156, 158, 160, 162, 164, 170, and 172. Since some of these pins pass signals that are used for the DVI interface on the industrial I/O board, I presume that those models aren't capable of providing DVI video output. Can you verify this is the case?
Thanks.

Wade,
Yes. The LX45 models cannot use the DVI interface as provided on the Industrial I/O boards.
The Industrial I/O board was developed prior to the LX45 SOM offerings came into existence, and because of the bonding issues with those pins we would have had to pick an interface that would have been sacrificed. So we elected to leave it "as is".
I am sorry for the inconvenience.""

The issue cannot be resolved without redesigning the PCB.
If you are using an LX-45, you cannot use the DVI interface on the dev kit. Why Xilinx did not bond out these pins remains a mystery.
I am sorry for any inconvenience.
