Notes: 4.
t
represents the time from the removal of CLK_IN by which CLK_IN must be re-applied to ensure that
CS
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.
6. fCLK_OUT = 24.576 MHz; Sample size = 10,000 points; AuxOutSrc[1:0] = 11.
7. In accordance with AES-12id-2006 section 3.4.2. Measurements are Time Interval Error taken with 3rd
order 100 Hz to 40 kHz bandpass filter.
8. In accordance with AES-12id-2006 section 3.4.1. Measurements are Time Interval Error taken with 3rd
order 100 Hz Highpass filter.
9. 1 UI (unit interval) corresponds to t
or 1/f
