Field Bits Type Description
DCA [7:0] rw Delay Compensation Channel A
1)
(pDelayCompensation[A])
Used to compensate for reception delays on channel A. This
covers assumed propagation delay up to cPropagationDelayMax
for Microticks in the range of 0.0125
µ
s to 0.05
µ

minimum of the propagation delays of all sync nodes should be
applied.
Valid values are 0 to 200 (0

CDD [20:16] rw Cluster Drift Damping (pClusterDriftDamping)
1)
Configures the cluster drift damping value used in clock
synchronization to minimize accumulation of rounding errors.
Valid values are 0 to 20 (0
