Notes:
4. t
CS
represents the time from the removal of CLK_IN by which CLK_IN must be re-applied to ensure that
PLL_OUT continues while the PLL re-acquires lock. This timeout is based on the internal VCO frequen-
cy, with the minimum timeout occurring at the maximum VCO frequency. Lower VCO frequencies will
result in larger values of t
CS
.
5. Only valid in clock skipping mode; See
“CLK_IN Skipping Mode” on page 13
for more information.
