JITTER GENERATION
Jitter Generation (Random Jitter)—49.152 MHz Crystal for System Clock Input
Table 18.
Parameter Min Typ Max Unit Test Conditions/Comments
JITTER GENERATION System clock doubler enabled.
High phase margin mode enabled.
Both PLLs are running with same output frequency.
In cases where the two PLLs have different jitter, the
higher jitter is listed. When two driver types are listed,
both were tested at those conditions; the driver type
with higher jitter is quoted, although there is usually not
a significant jitter difference between driver types.
