Tracking to the Input Sampling Frequency
When the ILRCK is generated by an external PLL, it may take a time to settle after changing the input sampling frequency
because the response of an external PLL to the frequency change is slow. AK4126 operates normally up to 23%/sec speed
and the output data becomes incorrect at the speed of the frequency change over 23%/sec.
