Sir, I would like to design a SFPDP module that receive parallel data from F/o module . This is a part of a recorder. My question is how to proceed with Stratix IV board? Can i use ALTGX Transceiver for that? If so please do mention challenges.

When i was using ALTGX,offset cancellation is automatically enabled and there we need this dynamic reconfiguration right? That's why i have created ALTGX_RECONFIG Instance.

Well, i can summarize my procedure like this

1. By using ALTGX i have developed a transceiver setup with 650 Mbps with 4 channel and 16 bit wide , also the protocol i have used here is XAUI
2. I have a 16 bit input data on each channel and i have to serialize encode and transmit on transmit side
3. Similarly the opposite have to be done in the receiver side of transceiver
4. In between the transmission and reception of data i have to frame and de-frame the data using user logic
5. This whole design is to design SFPDP (Serial front panel data port)

Problems facing

1. Developed the transceiver setup but i'm not able to de-serialize back the serialized output data from the transmitter by loop backing the data in user logic
2. Don't have much idea about dynamic reconfiguration using ALTGX_RECONFIG
3. The explanation available in the user guide is bit confusing
