Martin, you gave us the -8 option did you not? How about a -6 option so we can squeeze the data over the bus? Think SNR will be degraded too much in that case? Disclaimer: I know nothing about verilog/FPGA, and may have just asked a very stupid question. 8 bits sounds like a nice number, and 6 sounds less than convenient, but maybe it doesn't matter if it is truly a bit stream?
