Is it just me or is the documentation for the RocketIO (MGT) for the Xilinx Virtex4 very bad? I'm trying to find duty cycle requirements for the MGT clock. Is it OK to use a clock with a 40% duty cycle?
Also, if anyone can point me to some better RocketIO (MGT) documentation for the hardware guys I'd appreciate it. I already have ug076.
Thanks, Dale
