The device cannot tolerate prolonged operation at this absolute maximum. Refer to
The rate matcher supports only up to +/-300 ppm.
This parameter is measured by embedding the run length data in a PRBS sequence.
This feature is only available in PCI-Express (PIPE) mode.
Time taken to
This is how long GXB needs to stay in LTR mode after
asserted in manual mode. Refer to
Time taken to recover valid data from GXB after
results are based on PRBS31, for native data rates only. Refer to
