Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond
the listed limits may affect device reliability or cause permanent damage.
PLL supply voltage is specified at input of the filter and not at pin of the MSC8144 (see Figure 43 )
Recommended Operating Conditions
Table 3 lists recommended operating conditions. Proper device operation outside of these conditions is not guaranteed.
