Jitter Generation (Random Jitter)—19.2 MHz TCXO for System Clock Input
Table 19.
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. Where 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.
