Clock Data Recovery Stratix V (time needed)

Hi John. I am actually working on a project almost exactly the same as the one you described in the original post. Have you found any more answers? I have been playing around with resetting the RX reset controller in manual reset mode and measuring the time it takes in clock cycles to begin clocking in valid data. I am getting times much greater than 4 uS (nearly 100 uS!!). Perhaps resetting the entire PMA and PCS is not the correct way to measure the dynamic CDR synchronization time... Also, I believe that the burst mode receivers in OLTs require the ONUs to use the recovered clock as their reference clock for then transmitting data back to the OLTs. This is what allows for the nanosecond scale CDR time, because now all the CDR must do is detect the phase of the incoming data.
