NOTES: (1) Sysclk transient is the maximum frequency lock time when the PLL frequency is changed. (2) Dynamic performance specs are tested with 20kHz low
pass filter and THD+N specs are tested with 30kHz LPF, 400Hz HPF, Average-Mode. (3) SNR is tested at Infinite Zero Detection off. (4) PLL evaluations tested
with 1ns maximum jitter on the 27MHz input clock.
