Notes: 4.

f

CLK_OUT

= 24.576 MHz; Sample size = 10,000 points; AuxOutSrc[1:0] = 11.

5.

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.

6.

In accordance with AES-12id-2006 section 3.4.1. Measurements are Time Interval Error taken with 3rd
order 100 Hz Highpass filter.

7.

The frequency accuracy of the PLL clock output is directly proportional to the frequency accuracy of the
reference clock.
