Figure 12 - Manual Reference Switching
Two types of transitions are possible:
Semi-automatic transition, which involves changing RefSel input to select a secondary reference clock
without changing the mode select inputs MS2,MS1=00 (Normal mode). This forces the ZL30410 to
momentarily transition through the Holdover state and automatically return to Normal mode after
synchronizing to a secondary reference clock.
Manual transition, which involves switching into Holdover mode (MS2,MS1=01), changing references with
RefSel, and manual return to the Normal mode (MS2, MS1=00).
In both cases, the change of references provides “hit-less” switching.
5.2 Power Supply Filtering
Figure 13 presents a complete filtering arrangement that is recommended for applications requiring maximum jitter
performance.
