the Transceiver IPcore in Stratix IV GX can't work well

thanks Dave

yes,i have tried different data rate,1.6Gbps,2Gbps,4Gbps,5Gbps,8Gbps...sometimes it's all work well,but the result is not correct for most of times.

for the reference clock,i'm sure it's good. i use Oscilloscope to test the clock,and it's displays well.

the board is not custom board,it's made by ourselves,and we don't have any Altera reference board to compare .May be it's the problem of the board,but the pin Pins are connected correctly,and power supplies well.

i will try the way of SignalTap II to test if all the control signal is right.

i hope there is something wrong in my logic,but not the board.god bless...

thanks for your advice

best regards
