– Phase Shift
In the case the DPLL detects an edge in the data stream in the range of DPLL count 5 to 10
(Phase Shift) and this is the only one in the assumed bit cell period, then the DPLL receive
clock phase is shifted by a certain DPLL count value.

Synchronization of the Data Clock in DPLL Mode: Interference Rejection and Phase
Adjustment
The DPLL value and its corresponding phase shift in degree is listed below for the HSCX
versions VA3 and V2.1:
Note: The operating characteristics of the DPLL therefore allow a phase jitter of 18.75% of the
