Hi Chuck,
Ooopss, I've just clicked wrong button.. In fact, the problem is still 'alive'. I've made some tricks on timing costraint on FPGA. Works @65MSPS a little better, some bits are stable, some not!! For sure, the problem is not on the TI , also not on a Xilinx !! The Virtex deserializer source files (VHDL/Verilog) will be very welcome for all the groupers!!
Thanks,
Mariusz
