4.3. Input Clock Control
This section describes the clock selection capabilities (manual input selection, automatic input selection, hitless
switching, and revertive switching). When switching between two clocks, LOL may temporarily go high if the two
clocks differ in frequency by more than 100 ppm.
4.3.1. Manual Clock Selection
Manual control of input clock selection is chosen via the CS_CA pin according to Table 9 and Table 10.
